The second time I wore these, a small hole appeared by the big toe. It's the only one so far, and I like them besides that. Nice and thin but not too thin. Stay up nicely.

*UPDATE* the same day I posted this review, I got a message from the seller that they'd send me 2 extra pairs of socks. I've been wearing these socks daily and its still the only hole, so I assume it's just a fluke. Updated to 5 stars due to awesome customer service.
