adidas Copa Soccer Socks (1-Pair) Small

I wear a women's size 9 and bought a Medium. They fit comfortably without excess sock at my toes. These are double the price of the two pairs of "adidas Unisex Rivalry Soccer (2-pair) OTC Sock Team, Black/White, Medium US" for about the same price, but I ended up buying two more pairs of these "Copa Zone Cushion 4 Soccer" socks because: - the foot area is bigger and not as tight on the sides as the Unisex Rivalry socks. There is more room for my toes to stretch out. - the height of the knee high is slightly lower than the Unisex Rivalry socks which goes a little past the bend in my knee so I end up pushing the sock down or folding the top over. With these Copa socks, they fit comfortably below the bend in my knee. I am 5' 4." - the moisture wicking properties seem to be even better than the Rivalry: these Copa socks are: 98% Recycled Nylon, 2% Spandex Rivalry are: 93% Polyester, 3% Natural Latex Rubber, 2% Nylon,2% Spandex I am wearing these socks inside a walking knee height boot for my broken foot. My foot is less hot and sweaty and more comfortable. - There is more padding with these which seems to include the toes and heels. both have padding under the ball of the foot. I wore and washed both types of socks, my conclusions: - These socks held up better and did not shrink. They are still longer than I need, so they can bunch up behind my knee but they do not slip down as I walk. They are also a nice, warm layer on my legs for Winter. - The adidas Unisex Rivalry Soccer (other socks) shrank so the top was about 3" below my knee. These offered more padding for the foot and initially fit better, but after shrinking they kept slipping down as I walked.
