Looks like good quality socks true to size. However, I bought them because of the anti-slip feature. They have an anti-slip function (formulation), but it is not enough for the size of the floor. The non-slip part is a small stripe in the middle of the sock. My daughter's legs keep slipping out from under her and she falls. All of our floors are tiled so this is an important factor for us. Otherwise quality, feel and fit are all good.
