The Speed Force II from Xero Shoes is a redesign from their popular running shoes, with an upgraded breathable upper and welded components for added durability. The minimalist shoes provide a surprising amount of support, with instep straps that keep the shoe connected to the foot. Additionally, the 4.5-millimeter thick rubber soles are rated to last 5,000 miles.
