VIBRAM five fingers NWOT=NEW WITHOUT TAG/Box Optimal balance of traction and durability Responsive on unpredictable terrain Engineered for stability and comfort Additional Information DESCRIPTION: From day one, the FiveFingers Classic has drawn the attention of the press and active outdoor athletes alike.

Our patented original takes a minimalist approach to barefooting with a thin, abrasion-resistant stretch polyamide fabric that sits low on the foot for comfort and quick drying. A non-marking, razor siped Vibram XS Trek performance rubber sole helps protect your feet and provide a sure grip over a variety of terrain. DETAILS WEIGHT: Men's 43 = 6 oz., Women's 38 = 4.59 oz.
