Switchback ISO

Dial-in, log out.

For the Switchback ISO, we partnered with BOA Technology, creators of The Boa System, to take their dial lacing system and combine it with our ISOFIT construction to create a game-changing fit experience that quickly and easily hugs your foot. A low profile, full-length EVERUN contoured, midsole. has amazing flexibility and energy return while cradling and protecting your foot. The dual-density PWRTrac outsole combines a firmer center footprint with a softer, tackier perimeter for traction, allowing you to conquer all obstacles in your path.
