Foam rolling has become an integrated part of athletes conditioning regime as it enables them to stay mobile and recover faster from soft tissue fatigue. The hard inner sleeve of the adidas Foam Roller takes this approach to the next level by enabling you to roll and massage muscle tissue much deeper than is possible with soft rollers. Hours of testing goes in to every one of our products. The diameter and length of the roller enables you to spend the least amount of time rolling whilst massaging the maximum amount of muscle tissue.
