Bootie construction upper combines with a minimal midfoot saddle, creating a lightweight, unrestrictive fit that can be adjusted by tightening or loosening the laces. Stretch heel and loop conform to your foot and allow for quick and easy on and off. Full-length Fresh Foam midsole delivers plush, responsive cushioning, while an 8mm offset encourages a more comfortable and natural running stride. Lightweight blown rubber outsole for durable traction on any surface. Wt. 7.1 oz.
