The Nike Flex Trail is a cushioned trail shoe that will let you run hard on the trails while being easy on the wallet. An aggressive outsole features multidirectional lugs that provide solid traction, as well as cutouts in key areas for flexibility. A two part midsole offers underfoot impact protection as well as a responsive ride, while reinforced heel and toe overlays deliver lasting durability. Details such as a tight mesh upper and a gusseted tongue keep debris out, so you can focus on the trail ahead.
