An Update to a Favorite With Even More Cushioning
The Topo Athletic Ultrafly 5 upped the ante by adding even more cushioning to the midsole. By increasing the stack height by 2mm in the heel and forefoot, you’ll be moving in comfort all day long. The Ultrafly offers a dual-density midsole with a soft step-in feel underfoot and a more responsive foam closer to the ground for added bounce in your stride. With a slight medial post and an external heel counter, you can expect a reliably stable running experience.
Features and Benefits:
- Roomy Toe Box: Featuring Topo Athletic’s well-known anatomical toe box to allow your foot to spread naturally and comfortably
- Made with Recycled Materials
- Zip Foam: Topo’s proprietary midsole foam which is springier and offers more rebound than standard EVA

The Goldilocks shoe
I love the Hoka Arahi, but I wanted to find something with a more flexible sole and wider toe box. This is it. Way better than previous versions of Ultrafly.

I’m a new convert to these shoes! Super comfortable. I usually wear a 10 but 11 fit better in this style.
