Rain, snow, mud and cold are no match for the Kid's Arctic Sport™. The Arctic Sport™ is 100% waterproof and lined with fleece which offers a comfort range of 40° to -40°F. The durable natural-rubber shell and CR flex-foam bootie provide maximum protection for playing in cold, wet or muddy conditions. The easy-on/easy-off feature will make tracking snow and mud into the house a thing of the past. Boots from discount stores don't compare to the Kid's Arctic Sport™ from The Muck Boot Company.
