The fabric of the sock is too thin, worn out and a hole has appeared in less than a month.
The fabric on the left toe ripped after a month of socks. Haven't had this problem with any brand of shoe I've bought in the past. If you want I'll send them back for you to inspect the fabric. I just find it too thin.
Pros
A practice
Cons
Lack of stability is not the best choice for people with stability issues.
