These are difficult to review because comfort and fit are outstanding but, and it is a bad but at $7.50 a pair they are expensive; therefore, I would expect them to last. They do not. First, I ordered the first pair in May and there is already a hole at the toe in August! Second, they do not do well in the wash (hang dry) they start to fray. Finally, while Soxshop offers that socks may be returned and replaced if they do not meet expectations of robustness, they is no vehicle other than the normal amazon order cancellation to address the problem. I am afraid that I am dealing with meaningless hype as is so often the case these days.
