I bought two sets of these and opened both because I’ve liked HUE products in the past. Unfortunately, these don’t have enough non-slip material in them and they come right off. They seem to be too long from the center to the back for me. They are not snug in the back and they are too low, as well.Definitely slides off of your heel..but if you can get them to stay, they are comfortable socks.These socks do not stay on your foot when paired with sneakers. They fall off the heal and bunch up. Super uncomfortable!I like the Hue brand but am disappointed with these socks. The heel grip is not enough to keep the sock on my foot. It’s frustrating to have them slip off all the time. These socks are of no use to me this way.They stay on the toes but the hell doesn’t stay up at all!!!!These do not stay on your heels. Other then that they are decent socks.They fall of the plastic in the back doesn’t work. Horrible socksThese socks slip off your heels before you even take two steps after slipping them on... HUGE disappointment!
