Our new Vibram sole runner is made from a combination of soft calf suede for the body of the shoe and collar and supple milled calf leather around the toe, heel and facings. Milled leather is a tumbled, grainy textured leather with a soft feel. The style has a padded tongue and collar with a fabric lining and full cushioned leather insock. The Vibram sole has a cushioning CMR midsole in grey with a cleated black rubber tread outer sole.
