These boots are built like ski boots. I think they'll be great in the snow. I'm selling them because my child outgrew them without getting a chance to wear them much m(._.)m The size is listed as 11, but my son, who wears size 16, can wear them with socks on^_^ They fasten with Velcro, so they're easy to put on and take off, and they felt stable. It's also cute that the soles light up when you walk♪ They were only worn for a few hours, 1 or 2 times. Season: Winter
