Lacrosse redefines what a hunting boot can do with the AeroHead Sport Boots. These boots replace the traditional rubber shell with a polyurethane AeroForm Shell for a durable, lightweight, and insulating pair of footwear. The AeroForm Shell wraps the entire foot for all around cushioning comfort and insulation. The the upper parts of the AeroHead Sport Boots are constructed from Lacrosse’s Brush Tuff material, a combination of spandex and Lycra that is layered over neoprene to stand up to thorns and dense brush. In addition, the AeroHead Sport Boot is equipped with the Aero Sport Outsole, which is designed to keep you fast on your feet with non-loading tread that also keeps you steady on uneven terrain.
