More Boost, Incredible Energy Return: The Ultraboost 21

by Michelle L. on January 25, 2021

As we all know and love, the iconic adidas ULTRABOOST sneaker debuted in 2015, making its mark in sneaker culture. Not only was this boost technology and primeknit material new to its kind, it changed the shoe game to this day.

The new ULTRABOOST 21 is like no other. A team of leading designers and product developers worked closely with the adidas running community and testers to create the new ULTRABOOST 21 silhouette, which reimagines the original ULTRABOOST to deliver a bold new design combined with the latest in performance technology.

The core development in ULTRABOOST 21 is the redesign of the shoe’s torsion system. The new adidas LEP (‘Linear Energy Push’) provides a 15% increase in forefoot bending stiffness for a more responsive stride. This works alongside our proprietary midsole BOOST technology, which packs in 6% more BOOST through an exaggerated heel curve, providing runners with incredible energy return and comfort in every step. Lastly, it is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic. The perfect combination of weight, cushioning and stiffness, Adidas has created this incredible energy returning sneaker.

The new Adidas ULTRABOOST 21 collection drops online on February 4, 2021 at 12AM EST at Solestop.com. Shop from the classic Black/White, Triple Black, Triple White, Grey, and the new colourways below.
