My daughter only had ankle high socks. That just wasn't going to cut it this winter with all of the snowtubing and skiing we have planned. She got these socks wet about an hour into a 5 hour ski day by stepping in a puddle just before putting on her ski boots. Her feet actually stayed warm despite the socks getting damp. Bonus for coming up to just below her knees and STAYING THERE all day. These are her favorite socks now, and the only ones she will wear before embarking on outdoor winter activities. I'm getting more right now.
