Men's Topo Athletic Ultrafly 6 Running Shoes 11.5 Regular Grey/Navy

We freshened it up from top to bottom to amplify the comfort and light stability that's been the foundation of Ultrafly from the start. With even more cushioning than its predecessor, we redesigned the medial post to now wrap the heel to ensure smooth stability throughout. The ZipFoam midsole continues to evolve, now providing an even more responsive ride. Additional rubber coverage on the outsole improves durability and traction, while optimizing the inherent stability of the shoe.
