I have the mid-weight and the light-weight versions and really like them both. I thought these may be too light-weight, like some of the really super-thin ankle socks, but they aren't.  I actually like them better than the mid-weight. I have not owned them long enough to see how they hold up, but after wearing them several times I'm not too concerned.  I plan to eventually phase out my normal ankle socks 'cause toe socks are awesome. My toes love them!
