The interconnected air holes assist the closed-cell polyurethane foam structure to circulate air throughout the boot, creating constant air flow and increased levels of comfort. OrthoTec Air features anatomically designed arch support and an AirZone Comfort System® inside its soft yet stable polyurethane structure. This all creates a shock absorber like effect to absorb sudden blows and combat the degenerative effects of heel strike, which in turn enhances comfort and reduces fatigue. This footbed is our most popular and can be found in the majority of our boots. TheToughSider solegets going when the going gets rough!
