Speed up your run and eliminate distractions with the Under Armour SpeedForm Slingride. Strong, lightweight Dyneema fibers woven throughout the upper for supportive flexibility. Asymmetrical compression zones in the upper slingshot your foot forward from heelstrike to toe-off for a faster running stride. Padded mesh tongue adds comfort and improves fit. Dual-density Charged Cushioning midsole places a soft layer of foam over a firmer base for comfortable support that absorbs impact with every step. Full-length rubber outsole for durable, lightweight traction on any surface.
