Famous snow boot maker Sorel's top-of-the-line model, the Caribou. My child wore these, but they've outgrown them, so I'm selling them. They were only worn on snow, so there's almost no wear and tear on the heels. The size is 23, but they fit sizes 22-24. My child started wearing them around 22cm, but they weren't so loose that they'd slip off. Also, I, who usually wear a 24.5cm sneaker, can fit in them, but they feel a little small. Even at extremely cold ski resorts (like -15°C at night), my feet never got cold, so I highly recommend them! Compared to the slightly cheaper Sorel boots, which have a nylon upper, these are made of leather, so they're really warm. Waterproof snow boots made with natural rubber, leather, and fur. - Brand: SOREL - Model Name: CARIBOU - Color: Brown/Black - Materials: Natural Rubber/Fur - Waterproof: Yes Thank you for looking.
