The gym where you work out doesn’t have stationary bikes or a running track. Or a floor, walls, a ceiling or climate control. Siren Sport is an athletic shoe for women who stretch their limits on real ground under open skies. GORE-TEX® lining makes this shoe completely waterproof, but breathes, to wick away perspiration. The XCR® version keeps your feet comfortable in a wider temperature range. Vibram® Siren™ sole adds stability and traction you need for off-road running, speed hiking or trail biking. Q-Form™ triple-density molded footframe promotes healthy alignment for a woman’s stride.
