This product is useless to me because the material used to make them make my feet smell disgusting. The fact that they are extremely comfortable only makes the situation that much more frustrating. The last time my feet smelled this bad off of a pair of flip-flops was when I bought some for 5.99 at Walmart. Had I known the quality of material is equivalent, I'd have ordered those again instead. For prposes of clarification, I'm reviewing the men's sandals. The "Item being viewed" on my "create your review" page reads men's sandals but it says woman's sandals on my preview/edit page. A fitting end for my worst mistake on Amazon ever.
