Our fan-favorite returns with the legendary comfort and stability you’ve loved for years, now with more cushioning and an exciting new look. The Topo Athletic Ultrafly 5’s medial post and external TPU heel counter offer light pronation support for a stable and smooth run. We upped the stack height to 30 x 25 mm for 2 mm of additional cushioning. Our ZipFoam™ midsole delivers a lightweight and responsive ride, while our OrthoLite® Performance Insole provides a soft step-in feel. The recycled mesh upper provides a secure, comfortable, and breathable fit.
