Not quite my favorite socks

I've used it several times
True to size

For some reason these socks feel a little slippery inside my shoes, so I use them for road running and not on trails. I think I'll be going back to Feetures because of that.

Thick in all the right places

I've used it several times

I live in an area that gets to 100% humidity in the 80-100 F range during the spring and summer. Finding socks that can cushion on trails and aren't also thick as though it's cold can be difficult sometimes. These are perfect!
