The adidas Women’s Ultraboost 21 generates a linear energy push system with every step. What this means is that forefoot and midfoot stiffness increases through the stride to provide an extra energy boost at the end of your step.
The temperature independent ultraboost midsole provides huge levels of energy return even as your feet heat up through the run, where some shoes would get softer and less responsive.
A stretchweb outsole made from super grippy continental rubber moves with your footstrike to give a smoother and more flexible ride.
The Primeknit+ upper is highly breathable and moulds to your unique foot shape for a comfortable feel and personalised fit.
Primeblue products use at least 90% recycled material, including Parley Ocean Plastic intercepted from rivers and watercourses before it can enter our oceans.
