I purchased these socks for my daughter and they have become her go-to pair this winter. The thermal material keeps her feet warm and the colorful design adds a fun touch to her Girls' Fashion outfits. Based on my observations, these socks have held up well after multiple washes and have not lost their shape or color. The only downside is that they are ankle-length, so they don't provide as much coverage as taller socks. Overall, a great addition to any winter wardrobe.
