Winter's most wanted - Revel High GTX Warm! Winter wonderlands require warm boots to keep toes toasty with cozy insulation and waterproof protection. The ISA TanTec certified leather outer conceals a GORE-TEX membrane for breathable waterproof protection. The durable rubber outsole with grippy treads keeps feet stable and safe on slippery winter streets and playgrounds. We've thought of everything, from reflective details and velcro closures to XL pull-tabs they can use with gloves! The sole, ripstop, and ultra-durable mesh upper are all created from recycled materials.
