Adidas Ultraboost 21 Primeblue Running Shoes

Combining all of the brand's latest technologies and innovations with recycled materials, the Adidas Ultraboost 21 Primeblue are highly responsive running shoes ready to enhance any athlete's performance.

The Boost midsole has been re-engineered to include 6% more Boost capsules, giving a more energetic rebound to every stride and increasing cushioning across the most unforgiving surfaces. This midsole features an inbuilt LEP Torsion system, which acts as a springboard underneath each foot and heightens structural support. Underneath the midsole is the Continental rubber Stretchweb outsole that adapts to the runner's gait and the underfoot conditions to provide grip across any road surface.

A lightweight, breathable Primeknit upper cosily hugs the foot like a sock and markedly reduces pressure points. This upper is part made from Primeblue yarns that comprise Parley Ocean Plastic. This plastic is trawled from the sea, recycled and used instead of virgin polyester, helping to support the environment. The upper is partnered by a supportive heel counter that eradicates slipping at the rear of the foot. A traditional lace closure system completes the shoes by giving an even, pressure-free clasp.
