The AeroHead Sport completely changes what a rubber hunting boot can be by replacing the rubber shell with one made of extremely durable, lightweight, and insulating polyurethane. Designed for optimal fit and flexibility, the waterproof AeroHead Sport is built for ultimate comfort and will keep hunters light on their feet. Its Brush Tuff material stands up to unforgiving brush and briers while an abrasion resistant shin guard offers extra protection without added bulk.
