Buyer beware!!! SHUMADNESS does NOT stand behind their products & VIBRAM will NOT warranty their shoes unless you by directly from them. After 5 weeks of gym use ONLY, the sole separated from the upper, I sent pictures to both companies displaying the issue as well as the overall like new condition of the shoe, neither ShuMadness nor Vibram were willing to stand behind the product.  The color, fit and functionality of the shoe is amazing but for $160+ shoe I would expect to get at least 5-6 six months of use. Very disappointing experience.
