Too big!
These socks tun VERY large. I am a women's size 8.5 which should be a medium but they were way too large. I gave them to my partner who is a men's size 12.5 and they fit well. Definitely size down. Otherwise they seem like nice socks.
Love!
Love these socks, for me they do run a bit large. Wish I would have purchased the smaller size, but very good quality.
Mislabeled socks. These are ankles, not quarters.
They keep labeling the wrong socks. This is my third order of quarter socks that are actually ankle socks. Be prepared to return them.
need more colors!
Love these socks. They support my foot and are so comfortable. Wish they came in more colors
Not quarter socks
These are not quarter socks, as stated in the item description and the pictures. You'll receive low-cut socks.
Running socks
Good quality running socks. Very soft, good fit and cushioning.
Good solid socks
Fine socks, fit well, no problems.
