These socks are fun and do well as performance socks - moisture-wicking, light and comfortable. Collar is snug enough to stay in place but not so snug it cuts off circulation. These socks do run large... I wear women's 10-11 and bought a L/XL (10-14) based on the size chart because I was afraid of them fitting too small, but I think I could have used a S/M (6-10) instead. Either way, did not create any discomfort, just more of an annoyance. I think these socks are well-made but wish they were offered in 3 sizes instead of 2.
