The Women’s adidas Ultra Boost 20 “Grey” is a clean and versatile look for the celebrated performance running shoe. Dressed in grey and white accents, the ultra-comfortable Ultra Boost 20 features a sock-like fit with a soft and stretchy adidas Primeknit upper. The Torsion system within the midsole of the shoe provides a 15% increase in forefoot to heel energy for a more responsive run, and 6% more Boost foam capsules than the previous Ultra Boost model make for incredible energy return. A great highlight of the sneaker is that it is also made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic.
