Carry your Summer trail running into Fall and Winter with the Nike Air Jagged Ice trail running shoe. This shoe is built to turn back bad conditions without sacrificing performance elements so you have a good time even when the weather is challenging. A Gore-Tex® XCR waterproof upper blocks driving rain and soggy encounters with mud puddles while still allowing moisture vapor to escape. Innovative no-tongue construction also eliminates a common point of entry for water and debris. And to further reduce the impact of challenging conditions the Nike Air Jagged Ice men's trail running shoe features weatherproof lacing. Underfoot a full length Phylon midsole with a forefoot Poron foam pad and heel Air Sole cushioning unit provide a smooth ride whether the trail is frozen solid or you're faced with a multi-mile gauntlet of rocky terrain. Perhaps just as important as the Nike Air Jagged Ice's ability to shed water is the shoe's ability to provide traction on icy and wet surfaces. No problem here as the full length ORS 47 sticky rubber outsole with textured lugs dig deep in the mud and feel secure on wet surfaces too.
