Winter days require footwear that protects against cold and moisture. The Geox Trekkyup children's winter boots in brown are lined with wool and polyester fur. The upper is a combination of polyurethane and woven polyester. Amphibiox™ technology guarantees waterproofness and breathability, while Respira™ technology promotes moisture wicking. The shoes have a quick Velcro closure and a removable insole for easy maintenance.
