The Dri-FIT Tour TW combines proven Nike Air technology and a graphite sock liner to cushion and support the feet throughout a golfer's round. The visible Air-Sole unit in the heel and the low-profile, responsive Zoom Air unit in the forefoot offer excellent comfort without compromising balance and stability. The lightweight sock liner adheres to the shape of your foot and disperses your weight evenly and provides added arch support. It also offers comfort through the Nike Moisture Management System in the upper, made up of Nike's exclusive Dri-FIT inner layer and a Gore-Tex outer layer. The look of the shoe reflects Tiger Woods's desire for a refined, contemporary design. Full-grain calfskin leather, which features a two-year waterproof warranty, contributes to the sleek look while contributing comfort and support.
