Inspired by off-road bike tires, Under Armour teamed up with tire manufacturer, Michelin, for the Wmns Fat Tire 2 'Grey' sneaker. Released in January 2017, the women’s runner is designed for all-terrain performance and sports a soft-shell upper with rubber and waterproof finishes for resilient support. A Boa lacing system lets you make quick adjustments for a customized fit. The Charged Cushioning rests above the Michelin outsole to provide premium cushioning and traction on the trail.
