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.

Sizing way off
Size: One Size, Color: (100) White / White / Halo Gray
These were my favorite socks, at least the old style was. They redid them and I was okay with it. However, I don't understand how they are a one size fits most. I tried them on and they were still too big at the top. There was so much extra fabric at the toes. For reference, I wear a size 8.5 women's shoe, typically. The packaging says fits most from size 5.5 to 12. I don't understand how it fits that wide range of shoe size. Definitely returning these and I will be buying something else.
