I purchased these socks to wear with my Vibram 5-Finger shoes.  They are comfortable and lightweight, but they're not very durable!  After one 1 or 2 wears, I am noticing holes developing between the toes.  It's not even an area that stretches much, but it's beginning to rip.  For socks of this price, I'd expect to get way more than 2 wears from each pair.
