I bought these socks for my 20 month old son hoping he would have room to grow in them. Boy was I wrong. They fit the part of the foot well, but up to the ankle they are ridiculously tight. I tried pulling them up over his calves, folding them once so the top band was around his ankles, even just squeezing them, all to no avail. Regardless of how he's positioned, this staff will dig into his leg/ankle, leaving an ugly red stain. Otherwise the quality is excellent. Somewhere they make good socks
