The Air Stab 'Black Rustic' brings back the retro runner in premium leather with smooth color contrast. Created by Tinker Hatfield in 1989, the Air Stab was designed to stabilize the foot with a full-length series of support elements. They include a wide midfoot overlay, a series of slimmer overlays to create the toebox, and upper eyestays that provide a personalized fit and feel. Visible Air Sole cushioning is presented in a segmented theme for cushioning and old-school style.
