As my tests showed this pair of barefoot-style shoes truly enhances my workouts by maximizing the strength of my feet muscles. The lightness and flexibility of the shoe create an exciting freedom and natural movement, which definitely improved my speed and agility. On the other side, the toe box design has its drawbacks, as it may CAUSE rubbing if not well secured to the foot.Overall, a superb addition to any fitness enthusiast's footwear collection!See full review
