Good to know
- Formerly, the outsole material of the PureGrit 6 was made with blown rubber. Although this material delivers sufficient grip and durability, it was replaced with sticky rubber to improve the overall traction underfoot.
- Also with the same aim, the tread pattern on this Brooks trail running shoe was updated from hexagon shapes on the previous version to a mixture of hexagons and chevrons. Not only does the tread complement the grip delivered by the outsole material, but its grasp on multiple surfaces has also improved.
- The upper has been newly designed. One of the materials on this part of the shoe is heat-activated yarn which snugly wraps the foot without inhibiting its movement. On this new version, only one side of the shoe has the 3D rubber print. More specifically, it was placed on high-wear areas, while the other side has the air mesh material which promotes breathability.
- The new Ariaprene tongue was designed to keep debris and dirt from entering the shoe. Aside from its protective purpose, it’s also quick-draining which means that it quickly eliminates water, aiding in keeping the foot dry.
- Instead of the traditional laces which go straight towards the toe box, the lacing on this new version curves inwards slightly. This will be apparent when a runner looks at PureGrit 6 and PureGrit 7 from the top view.
The Brooks PureGrit 7 is available in standard shoe sizes. Runners can order a pair using the standard sizing schemes for running shoes. The width, on the other hand, is available in medium or standard measurements.
The main material the outsole is made of is called sticky rubber. It was designed to be a bit on the softer side, so it sinks into even the smallest divots and forms around bumps of varying shapes, thus creating more surface contact. It is through this dynamic that it prevents runners from slipping, providing better traction on the trail.
For the runner to feel more confident and secure while trail running, 3D lugs with hexagon and chevron shapes compose the tread underneath the shoe. The hexagon lugs vary in shape to adapt to any ground condition. The chevron lugs, on the other hand, go on different directions for better braking and traction when toeing off.
The Brooks PureGrit7 has the BioMoGo DNA cushioning on the midsole. This same cushioning is also featured in the popular Brooks trail running shoe, the Cascadia 13. BioMoGo is a biodegradable and more eco-friendly foam. Brooks has combined this foam with another one of their patents, called DNA. Commonly, the Brooks DNA is made up of a gel that adapts to the amount of force it receives. However, with the BioMoGo DNA, the gel inserts are replaced with BioMoGo foam, making the cushioning friendlier to the environment, while still providing runners with a responsive and adaptable ride.
Omega Flex Grooves were incorporated on the midsole. These indentions form segments that allow specific structures on the midsole to move with ease. This benefit is delivered without compromising the midsole’s cushioning and responsiveness.
To provide extra protection, the durable Ballistic Rock Shield was added. This thermoplastic EVA sheet can be found between the midsole and the outsole. Its primary function is to protect the foot from being injured as the runner steps on objects on the trail that are protruding or jagged.
The Brooks Ideal Heel design was also assimilated on the back part of the midsole and outsole. To make the running transition as smooth as possible, the outer heel was made to curve. While in motion, this design encourages runners to execute forefoot and midfoot striking.
The flat knit upper was made with heat-activated yarn. Commonly, some types of knitting textiles stretch with repeated use. What the heat-activated yarn does is ensure that the flat knit doesn’t stretch too much, retaining the upper’s shape despite consistent usage.
3D rubber overlays were placed on high-wear areas of the PureGrit 7’s upper for extra protection and durability. The Brooks logo can be found on one side as well. Aside from protecting certain areas, these overlays also have an aesthetic purpose.
Formed on an anatomical last, the upper provides a sock-like fit. It was formed to follow the natural contours of the foot, allowing enhanced comfort and delivering the right amount of snugness.
Just like the heel part of the outsole and midsole, the heel on the upper is also rounded. This allows the runner to have better body alignment, thereby minimizing joint stress and lessening the chances of injury.
The tongue is made up of a material called Ariaprene. Not only does it enhance the fit, but it also helps drain water during trail runs. It acts like a second skin while keeping dirt and debris from entering the shoe.
The front lace up design is unlike typical lace closures. Aside from being made up of a combination of holes and loops, the placement directs the laces towards the inner side of the foot. This design secures the fit better, allowing the runner to move confidently over the trail.
