HOKA ONE M SKY TOA Taking advantage of the expertise and innovations of the Hoka One One Trail Running, we have built a lightweight waterproof hiker in class for adventurers on any terrain. Everything about the Toa has been evaluated by a functional perspective and weight reduction. From the durable and breathable synthetic upper, foam midsole and the flaps of the Vibram Megagrip sole, all the elements are technically solid and efficient.
