The 9 stays true to the collection's lightweight, springy design and smooth ride by retaining the torsion system in the midfoot, but finishes off this responsive shoe with a new mesh upper and a more dialed-in fit. Their cloud-like feel will have you adding mile after mile to your routine. Women’s size 7.5 Preowned but great condition!
