Adidas Ultraboost 21 Running Shoes
The Adidas Ultraboost 21 Running Shoes amalgamate several innovative attributes to support any athlete in their search for elevated levels of pace and endurance.
Adidas has re-engineered the Boost midsole to contain 6% more Boost capsules for heightened rebound and energy in every stride and to increase cushioning across the most unforgiving road surfaces. The brand’s LEP Torsion system has been integrated into the lightweight midsole, and this acts to deliver increased spring, giving extra propulsion to the runner’s gait. Underneath the midsole is the Continental rubber Stretchweb outsole that is grippy and confidence-inspiring across all road surfaces, even when it’s raining hard.
A Primeknit upper has a supple, woven construction that is highly breathable and donates a supremely comfortable sock-like fit. This upper is realised via recycled Primeblue fibres that are made from Parley Ocean Plastic that is trawled from the sea. A supportive heel counter clasps the rear of the foot to eliminate unwanted movement while a traditional lace system closes without any peak pressure points.
