The Challenger is HOKA's all-around runner that performs just as well on the pavement as it does off road. The highly cushioned midsole delivers mile after mile of comfort and excellent support. For the outsole, HOKA used a pattern of flattened lugs that grip in the dirt but create a smooth ride on the asphalt. Plus, the updated version 6 features tons of recycled materials in the uppers, making them more eco-conscious. The outstanding versatility of this shoe makes it ideal for Eastside runners whose training laps include some back road, dirt roads, and single track.
