The Elite Assault Boots from Oakley were built to last without sacrificing comfort. The 8-inch upper suede is made from Cordura which allows for free range of movement and can help vent off excessive heat with its breathable fabric. The Elite Assault Boots come with a Vibram SPE midsole that provides comfort and shock-absorbing cushioning. These boots also feature Oakley’s lace-lock system with braided nylon laces to keep them on all day.
