Topo's fan-favorite returns with the legendary comfort and stability you’ve loved for years, now with more cushioning and an exciting new look.

Their ZipFoam™ midsole delivers a lightweight and responsive ride, while the OrthoLite® Performance Insole provides a soft step-in feel. The recycled mesh upper provides a secure, comfortable, and breathable fit.
