Inov-8's first-ever ultra shoe eats the hard miles for breakfast. The two-arrow Race Ultra™ offers optimal cushioning and comfort for the long-distance athlete, without the loss of proprioception. A flatter outsole ensures a stable ride when athlete fatigue sets in. Clip a gaiter onto inov-8's unique on-the-shoe attachment system to ensure all debris is kept at bay. The addition of an X-STATIC® footbed means that bacteria which feed on human sweat are kept at bay.
