Saucony PowerGrid Cortana Introduced to Saucony’s Growing Line of Minimalist-Inspired Shoes

With the recent trend amongst the running shoe manufacturers to introduce a “minimalist” shoe, there are now plenty of options for the light-footed runner who is after a little less on their foot. Here we take a look at a new option from Saucony. This is the brand who has recently brought us a myriad of “reduced drop,” lightweight shoes including the Progrid Kinvara, the Progrid Mirage and the new super minimal Hattori.

Published

on

The (already award winning) PowerGrid Cortana has been released as a “supportive cushioning” shoe. When compared to the popular ProGrid Kinvara, this shoe feels a little more substantial, and hints at a slightly longer lifespan. However, it remains a super light training option, weighing in at about 300g (Men’s size 9.5), falling closer to a “lightweight trainer” than a traditional cushioned neutral shoe (ASICS DS Trainer – 285g; neutral trainer option from ASICS the Gel-Nimbus – 340g).

The Cortana maintains the same reduced pitch as the previously released and hugely popular ProGrid Kinvara. Technically, this means there is less of a height differential between the heel of the shoe and the forefoot. This is a key aspect of minimalist shoe design, that, surprisingly, is often missed. To put this into perspective, Saucony has given the Cortana a 4mm drop – sitting your heel just 4mm above the forefoot. This is the same height differential that is common to many racing flats, whereas a traditional “neutral trainer” would typically have a 10-12mm height differential. This can’t be understated – in the Cortana (as in the Progrid Kinvara/Mirage) this 4mm drop is over 60% less than in a normal neutral training shoe. In terms of “feel,” this helps to encourage a more natural gait, and allows the runner to easily incorporate a little more “forefoot” emphasis into their gait, without really trying. Nice.

Fit and Feel

The upper incorporates “Sauc-Fit” – basically helping to lock the heel and mid-foot onto the midsole platform. This translates into a snug fit overall. There’s enough forefoot width, while at the same time I’m not left swimming in the shoe. The material feels breathable, but a little more secure than in the Kinvara – which some have found to be not quite as much support as they are looking for in a training shoe. The “Comfortride Sockliner” is an exclusive open cell foam sockliner, is antimicrobial (always nice) and seems pretty breathable.

Midsole

For someone coming out of a “normal” shoe, this will feel light, with a lot of forefoot emphasis and less rigidity than some of the more structured shoes on the market. The shoe incorporates Saucony’s PowerGrid with PowerFoam technology, which basically means it’s light, and provides the runner with great cushioning and a responsive feel.

Outsole

The PowerGrid Cortana has an IBR blown rubber compound in the outsold. This is hard wearing and will provide a bit more durability than the ProGrid Kinvara, falling in line with Saucony touting the Cortana as a bit more of a high mileage option.

Colour and Appearance

The shoe looks reasonably progressive and “racey,” but holds onto the roots of a traditional trainer. Despite the shoe having a bit more of a forefoot emphasis, Saucony have still played on the aesthetics of having “heel technology” by changing the colourway of the midsole through the crash-pad of the heel. This hints to the consumer that although the shoe is light and flexible, it is going to forgive you for the odd heavy heel-strike and suit a variety of runners. Personally, I’m not sure about the new “hue blending” that is popping up on a lot of shoes these days. Call me a traditionalist, but I prefer the stronger, more block colours. Overall though, the men’s model looks as good as any of the shoes on the market at the moment, and the women’s model looks edgy and a little brighter, perfect for the brighter days ahead.

The Run

Having been notoriously picky about my shoes, I approach new models with a bit of reservation. I often find myself thinking “what would someone else think of this” rather than: “what do I think of this?” Not this time. I put the shoe on, it feels natural. There’s enough width in the forefoot, the 4mm drop feels good. I’m reminded of a more forgiving, cushioned version of the Saucony Grid Type A4 racing flat from – a long-time favourite. The shoe feels very cushioned, but I feel flat, level and naturally positioned. Heading outside and I start to tick over a few strides – it feels natural. I can maintain a quick turnover, the shoe allows me to run tall, and I don’t have to force my form. It comes easily.

The run continues for a hilly 11km. The shoe feels cushioned, light, responsive and most importantly to me: natural. As a big fan of some of the more minimal approaches to running shoes, the PowerGrid Cortana stacks up well. It’s a softer, more forgiving option for sure – but when compared to the more traditional neutral high mileage training shoes, feels like a high performance machine.

Who’s It For

The Saucony PowerGrid Cortana is a great shoe for the runner who is conscious about running efficiently, wants a lightweight, high-mileage training shoe and wants it to last a little longer than some of the other models out there. The Cortana will help a range of runners run smoother, with a quicker turnover and less impact. There’s enough cushioning under foot to be a great option for a slightly bigger runner or someone who is just starting to work on their running form. It also will make a fantastic longer distance “natural” training shoe.

With a more neutral platform, it may be less suited to someone who is traditionally a heavier pronator, although the footbed seems to have ample room to accommodate an orthotic. Furthermore, a runner who generally uses more pronation control and is used to a heavy focus on the heel cushioning in their shoe may benefit from the reduced pitch and increased flexibility that the Cortana offers.

I’ve been waiting patiently for the release of Saucony’s Cortana and I haven’t been disappointed. It’s great to see a top-end, neutral training shoe incorporate some progressive design features that have already seen phenomenal success in Saucony’s minimalist inspired range. The reduced drop in the shoe, it’s lightweight feel and flexibility all combine to produce a shoe that is different from anything else that is out there at the moment. Different in a good way!

Shoe Type: Neutral Cushioned

Price: RRP $259

Weight: ~300g for men’s size 9.5, ~27g for women’s size 8.

Summary

With the recent trend amongst the running shoe manufacturers to introduce a "minimalist" shoe, there are now plenty of options for the light-footed runner who is after a little less on their foot.  The benefits of running in a more minimal shoe can be widespread, whether we look at traditional racing flats, or the new generation of "barefoot" shoes. A "closer to the road feeling" can be achieved, as well as a more natural gait pattern. Claims of fewer injuries, faster times and a more enjoyable running experience are often heard.

However, this is not another article on minimalist running, that's for a different day. Here we take a look at a new option from Saucony. This is the brand who has recently brought us a myriad of "reduced drop," lightweight shoes including the Progrid Kinvara, the Progrid Mirage and the new super minimal Hattori (stay tuned for write-up on this ultralight option!). This is also a brand that has had it's heart and soul in running from the start. The Jazz, Hurricane, Triumph and Grid Type A series were all brought to us by Saucony. In short, these guys know their running and know their shoes.

Review: SunGod PaceBreaker sunglasses – Look Cool While Dropping Watt Bombs

Published

on

SunGod sunglasses are a relatively new player to the market, a successful, UK based, crowd-funded business who’s appeal is focused on the ability to customise the glasses online at an affordable price.

SunGod was founded in 2013 and developed from a frustration that to get quality lenses that would be able to withstand a sports/adventure lifestyle.

They launched their first product, SunGod Classic, as their first complete custom online build, with polycarbonate polarised lenses and TR90 memory polymer frames. This campaign exploded, with SunGods being shipped to 93 countries and making 10x the initial funding target and becoming the largest crowdfunded project of its kind in the UK.

Simple to use interface, customise away.

Jumping on to the website is simple enough, and you get to choose from a variety of frames and styles. The Classics and Renegades focus more on traditional streetwear, extreme sports etc., while the Revolts are focused on snow sports. All of the range bears the funky looking Limited editions, are fully customizable.  As triathletes wouldn’t be seen dead wearing non-race specific gear, we’re going to focus the review on the PaceBreakers – wraparounds focused on riding and running (swimming not tested!)

What design do you ask?

I was lucky enough to get to design a pair of sunglasses via the simple to understand interface. Simple enough in fact that my five-year-old daughter created my first pair below.

From idea….

To reality…!

Going through the interface, you get to choose the frame colour, lens type (4KO Polarised or not – more on that later), icons on the side and ear sock colour (the tips of your glasses). If your creativity is failing you, you can also choose from a set series of best sellers.

The whole process takes around 30 seconds of effort with 20 minutes of procrastination around the right colours to match with your complexion and handbag.

My second pair was a much more straightforward affair focusing on the traditional grey look.

Got to have grey in Melbourne.

The glasses ship from the UK and for me, turned up in 3 days, a surprising and welcome change.

What’s in the box?

SunGod indeed go above and beyond with the packaging and its contents

Funky looking box

As you would expect you get a box with the sunglasses included, but you also get a spare nose clip, a case which also doubles as a cleaning rag and a truckload of stickers to stick around the place. Its quite a few freebies given the low cost of the product.

Quite the haul

4KO pace lens with triple scratch resistance

SunGod claims that the polarised lens is both triple scratch resistant and will enhance both visibility and field of view in both low light and bright conditions. We obviously couldn’t test them in a lab with serious equipment, but we took the glasses out on a treacherous, wet and windy early morning Melbourne ride around the Dandenong mountains in peak hour traffic.

Compared to my Jawbreakers I certainly felt that their visibility in early morning sun up (6am) conditions was improved.  The lens also survived being bounced along the road at high speed when I forgot to put them back on during a decent, with no scratches if I may add.  So science aside, these sunglasses certainly did the job during a challenging day out.

What differentiates SunGod from the competition

SunGod has a few key differentiated points.

Firstly is the price. For around $110 – $130 dollars you get a solid pair of high-performance sunglasses with features to match and outperform glasses twice their price.

The glasses come with a lifetime warranty so if they break they will replace them free of charge. A lofty claim that I haven’t tested but certainly a welcome one – which some of the major players struggle to offer.

The glasses are made from adventure proof flexible rubber which allows the frames to be flexed, and as above bounced along the road, without damage. Which as a clumsy guy is a great feature.

Overall

Simply put, SunGod makes a great pair of sunglasses, both comfortable and high performing, you cannot beat them for value. The customisation feature is excellent and has got my triathlon team all lining up to get the team colours shipped over. I didn’t have anything negative to say about them, to the point where I’m replacing my tried and trusted jawbreakers with these for both racing and training.

A Wearable RFID Fitness & Calorie Tracker that Mounts to Your Teeth

Published

on

Fitness and calorie monitoring technology is getting interesting. Researchers at the Tufts University Biomedical Engineering Department are experimenting with wearable trackers that mount to your teeth. The tiny monitors use Radio Frequency ID (RFID) technology to track calories, alcohol consumption, multiple types of sugar, and the foods you eat. The researchers also speculate about developing the devices to monitor stress levels from saliva.

The trackers use a square tooth-mounted sensor that is either 4 X 4 or 2 X 2 millimetres. They’re made of titanium and gold and feature detector layers made of either water-based gel or silk fibres.

When testing for the trackers’ ability to detect alcohol and sugar, researchers instructed subjects to swish various liquids. The trackers sent accurate information to tablets and cellphones, distinguishing between liquids such as saliva, water, and alcohols, as well as different types of sugars and their concentrations. Using water-based gel sensors, they were able to track varying temperatures and acidity levels.

These trackers could be a new breakthrough in calorie and fitness tracking. They are not yet available commercially because the researchers are still working out a few kinks and discovering more uses for them.

The Tufts study will be published in the journal, Advanced Materials. For now, you can read it in the Wiley Library below. The paper goes into detail about all the possible uses and the chemicals and nutrients these trackers will likely be able to detect.

Shimano Introduces Chain Stabilising Rear Derailleur for Road Bikes

Published

on

As road bike riding diversifies towards multiple road surfaces such as adventure and off-road riding Shimano introduces Ultegra RX, an off-shoot of Ultegra, with a rear clutch derailleur (RD-RX800/RX805) for mechanical and Di2 drivetrains.

Riders have been pushing the limits of what a road bike is capable of riding for many years, evolving the sport from racing to encompass greater adventure. In recent years we’ve seen a broader definition of what a drop handlebar bike can look like; road wheels followed that by accommodating wider tyres. Now in a natural evolutionary step, it’s time for drivetrains to evolve too.

Shimano RD-RX805 rear derailleur with clutch

The new RX800/805 rear derailleurs share many characteristics with the Ultegra R8000/R8050 derailleur, such as precise accurate shifting and SHIMANO SHADOW RD derailleur positioning, but with the added chain stabilizing switch (known as SHIMANO SHADOW RD+ technology) to control the drivetrain over rough/uneven ground or off-road surfaces. Much like Shimano’s MTB derailleurs, the On/Off switch can be found next to the upper pulley. When activated the rear derailleur pivot takes a firm hold to reduce excessive movement, noise and general ‘chain chatter’.

The RX800/RX805 rear derailleurs are compatible with road dual control levers (mechanical or Di2) and will accommodate cassettes with low gears from 28T to 34T, making them a very necessary addition for all types of adventure and off-road riding including cyclocross and compact styles with 46T-36T up to 50T-34T chainrings.

Alongside the Ultegra RX rear derailleur comes a new wider rim 700c, E-Thru axle, tubeless-ready, disc-specific, WH-RS370-TL aluminium wheelset for 28-38c tyres (weight 1900/pair).

You can expect the new components to be available in stores from mid-June 2018 onwards.

Shimano 105 R7000 Offers Race-inspired Performance for Greater Riding Styles

Published

on

Today’s road riders demand much more than pure on-the-rivet speed. They expect comfort, control and versatility from their bikes, and enjoyment and goal achievement to boot. 105 level riders expect the latest pro-level features but they also want to do more with their bike than racing and training.  So step forward the new 105 R7000 generation with customizable disc or rim brakes and wider cassette options to help you remain in comfort and control wherever you’re riding.

Coming with the high-end aesthetic and race characteristics of its Dura-Ace and Ultegra big brothers, the new 105 series also considers that most riders will use their bikes for purposes other than competitive racing. 105 is Shimano’s first level 11-speed groupset for those who are seriously committed to road bike riding, but that definition now becomes broader with the inclusion of superior handling and adaptable control to master different riding situations.

The biggest news for new 105 is the addition of disc brakes to the series line up. New flat-mount BR-R7070 callipers are compatible with ICE TECHNOLOGIES pads and UCI-compliant non-90 degree SM-RT70 rotors (including a new 140mm size) to offer greater cooling efficiencies. Brake operation is handled by new ergonomically shaped Hydraulic dual control levers (ST-R7020), matching the design of Ultegra ST-R8020 levers with a greater range of reach adjustment for different hand sizes. To provide even greater customisability, 105 R7000 offers a version of the dual control brake/gear lever (ST-R7025) to better suit smaller hands by being angled closer to the bar and taking more of an outboard position for better connection and to avoid interference with the handlebar drop during lever operation.

Whether from the rim brake (ST-R7000) or disc brake (ST-R7020/25) lever, gear shifts have been redesigned to offer faster and lighter shifts with a shorter stroke compared to the 105 5800 series. The front derailleur has a compact toggle (pivot) design, better tyre clearance and an integrated cable tension adjustment port (2-mm hex key) removing the need for an in-cable barrel adjuster. The optional long cage rear derailleur (RD-R7000-GS) can accommodate up to an 11-34T cassette and is designed with a low profile SHIMANO SHADOW RD style to tuck it below the cassette and chainstay.

Updates within the drivetrain include a new mid-compact 52-36T crankset, to add to the 50-34T and 53-39T cranksets, and new 11-30 (CS-R7000) and 10-speed compatible 11-34 cassette (CS-HG700-11) options to better suit gravel, adventure or CX riding. Together with this, the inner crank ring has been positioned to reduce the effects of cross chaining or chain drop, better suiting bikes with disc brake criterium racing bikes.

Tim Gerrits, product manager at Shimano Europe said;

“Increased control and reaction were two points we concentrated developments on, combined with what people have always expected from 105, great versatility and value for riders. With 105’s suitability for a large portion of today’s diverse road bike styles we hope to unlock the potential of where and what it’s possible to ride on a road bike.”

New Shimano 105 R7000 items will be available on the market around June and will be available in an appealing dual tone black colourway and an additional silver option for more classic bike styles.

Ventum is expanding its line of cutting-edge triathlon racing bicycles

Published

on

Built around the company’s patented Z-shaped frame design, which eliminates the downtube and seat stays while integrating the water bottle into the frame, the expanded Ventum Z line was developed to allow more triathletes to enjoy the aerodynamic advantages of Ventum technology.

“We designed our flagship triathlon bike, the Ventum One, for the toughest races in the sport,” Ventum co-founder Diaa Nour said, “and we based the new Ventum Z models on feedback from triathletes, who told us they want access to the same technology developed for the Ventum One, but with more flexibility to customize the bicycle to fit their needs.”

The new Ventum Z includes Ventum’s patented Z frame plus a proprietary carbon-fibre Z fork and is available for purchase as a standalone frameset for $2,850. The Ventum Z is also available as a complete bicycle with a mechanical component group featuring a combination of Dura Ace, Ultegra, and other Shimano components for $3,500, and as a complete bicycle with Shimano’s electronic Ultegra Di2 component group for $5,500.

“We wind-tunnel and road-tested every component of every version of the Ventum Z to find the perfect balance between aerodynamics, comfort, and cost. Our goal in reimagining the Ventum Z was to make a more affordable ‘superbike’, and to keep it cutting-edge without cutting corners,” Nour said. “To do that, we developed our new, proprietary Z fork, we included a custom set of 3T Vola aero bars for easy positioning and adjustment, and we are offering a choice of carbon-fibre or alloy wheels that are optimal for the bike.”

Ventum was co-founded in 2014 by Diaa Nour and former professional triathlete Jimmy Seear, to build the world’s fastest racing bicycles. Inspired by fighter jets and Formula One race cars, the company’s triathlon bicycles feature a revolutionary frame design that maximizes aerodynamic performance in non-draft-legal races such as IRONMAN and IRONMAN 70.3 triathlons. Ventum also served as the Official Bike Sponsor of the 2016 and 2017 IRONMAN World Championships in Kona, Hawaii. Based in Miami Beach, Florida, Ventum bicycles are available worldwide through the company’s dealer network and from the Ventum online store.

DeFeet to Use Blockchain Technology to Stop Counterfeit Products, Improve Customer Experience

Published

on

DeFeet International, a manufacturer of socks and other apparel for cycling, running, and outdoors activities, has partnered with blockchain solutions provider, LuxTag.io.

The new technology will accomplish a few goals that help both the company and the customer. When you receive a DeFeet product that is in a blockchain, you’ll be able to scan it with your phone.

Scanning your DeFeet product will:

  • Ensure the product is not counterfeit
  • Add it to your customer profile
  • Help DeFeet suggest products relevant to your individual behavior & taste
  • Take some hassle out of the warranty & repair process
  • Determine appropriate loyalty rewards
  • Help determine distribution logistics

The overall result is a better and safer customer experience.

The first roll out will cover the company’s Barnstormer line. They’re focusing on matching their Adventure Cycling Club members with relevant products and promotions based on past purchases and other data. Current promotions reward members who complete missions. They’ll expand the practice to more product lines over time.

What is Blockchain Technology?

If you don’t know what blockchain technology is, you may have some trouble comprehending what DeFeet’s new changes mean for customers. Pay attention here, because you’ll be seeing and hearing the term a lot from now on.

The anonymously-invented technology was created in 2008 for Bitcoin, a cryptocurrency. It ensures the authenticity of transactions by decentralizing the locations of documents. This helps people verify the transactions publicly and prevents hacking and counterfeit.

The block in blockchain is a record that shows:

  • Medical info from your doctor
  • The location of your cryptocurrency
  • You voted in an election & who received the vote
  • You bought or sold Bitcoin or a pair of athletic socks & the transaction value
  • You made a bank-free transfer of money or received one

Think Google Docs. Multiple actors can create a document together, and the document is not stored on anyone’s individual computer. In the old days of document collaboration, you had to save it to your computer, edit it, and then email it to another editor. The other editor then had to make edits or comments and send it back to you. In Google Docs, if someone makes an edit, all editors can verify that in real time and even look at the change records. You can set the document to be visible only to certain people, and to allow only one person at a time to edit it.

DeFeet Leads the Way for Retailers Considering Blockchain

Certain sectors of the business world have recently taken an interest in blockchain solutions. Digital ad companies want to distinguish ad views by humans vs bots. Manufacturers want to trace problematic product parts to their sources. Cryptocurrencies want to authenticate transactions and trace the whereabouts of the currencies. Wire money transfer companies want to cut down on costs and pass the savings to users. Voters want to know their votes have been counted.

Retailers have been slow to jump on the blockchain bandwagon. Expect more retailers to follow Defeet’s lead.
