“These are the best running socks I own. Have tried Rockay and Saucony. Like both of them, but, once I bought the Swiftwick Maxus One's these are the only ones I want to run in now. I, like most runners do not wash my socks after every run. These do not stretch out and stay tight every time. No excess bunching up behind my toes either. Can't speak on the longevity of them yet but my running buddy has pairs that are over 5 years old. I have quit looking for the best pair of socks now. Others may not feel the same as me but I love these and will only by them from now on.”
