This abrasion-resistant 1000™ outsole's equipped with a high-resolution siping pattern that promotes a neutral ride as well as strategically placed segments of solid rubber to enhance traction in high-wear areas. Plus, it looks great with jeans for street wear, for those who favor an athletic look all the time. Wt. 7.4 oz.
