Topo Athletic Running shoes Ultrafly 6

We have completely redesigned it to enhance the comfort and lightweight stability that have always been the foundation of the Ultrafly. Featuring even better cushioning than its predecessor, we have reshaped the medial support so that it now wraps around the heel to ensure smooth stability throughout the stride. The ZipFoam™ midsole continues to evolve and now offers an even more responsive stride. An additional rubber reinforcement on the outsole improves durability and grip, while optimising the inherent stability of the shoe.
