From day one, the FiveFingers Classic had drawn the attention and praise of the press and active barefoot enthusiasts alike. This original design takes a more casual and minimalist approach to barefooting. The upper features a thin stretch nylon fabric that fits low on the foot. The non-marking 3.5mm Vibram TC1 performance rubber soles are razor siped for improved flexibility and slip resistance over a variety of terrain. Available for men and women. Machine washable - air dry. Use for fitness training, crossfit, travel and after sport.
