Love these socks!
The wife struggles with socks. She only like the Nike ones, then they discontinued them, so had to start the search again! Found these, they are expensive just like the Nike, but the size is true, they look great, they are super soft and stretchy. They are light weight and breathable and seem to wick away moisture. She loves these!

Lasts a while for the price
Number of Items: 6, Color: White (6-pairs), Size: Large
Honestly, the best quality socks for the price. Last a long time and lots of sport and non-sport usage. Trim your toe nails though, this isn't immune to dank toe nail care.
