Runners everywhere are no doubt thrilled that adidas has announced the upcoming release of the ULTRABOOST 21, the latest iteration of the brand’s bestselling running shoe, the ULTRABOOST. The technical team at Adidas came up with a new design for the shoe, a torsion control system called ‘Linear Energy Push’ (LEP), which is essentially a horseshoe-shaped plastic insert that sits underneath the midsole. Because it is stiff, it acts as a reinforcement, says adidas, providing runners with less flex in the forefoot and increased responsiveness. It not only gives a snappier push off the ground but also helps to subtly guide the foot more quickly through the gait cycle and allows less time for overpronation to take place. Apart from the LEP, the adidas ULTRABOOST 21 are based on the company’s proprietary BOOST technology, producing a 6% additional boost in stride thanks to an exaggerated heel curve.
In addition to the advances in comfort, support, and energy return with this shoe, adidas maintains its commitment to sustainability and protecting the environment by making the ULTRABOOST 21s with recycled material, by using a minimum of 50% Parley Ocean Plastic. There is zero virgin polyester in the shoes, thanks to the use of recycled materials. Stretchy and fitting like a comfortable sock with a lace closure, the adidas ULTRABOOST 21 will be available to purchase in a white and fluorescent yellow colorway on January 28th.
