Excellent sport sock!
Size: One Size, Color: (100) White / White / Halo Gray
Molds onto foot, super soft and breathable. A lot of my ankle socks tend to slip or cut off blood circulation. This one literally is a perfect fit. No slip. After playing hours of tennis every week, my feet don't feel sore or bruised. Must buy!

Comfort!
Size: One Size, Color: (100) White / White / Halo Gray
Very comfortable! Thinner than the picture shows, but I like the fact that they are no show but still higher in the back and front to protect my heels and such.
