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, creating a game-changing fit experience that quickly and easily hugs your foot. The low profile, full-length EVERUN contoured midsole of this trail running shoe gives 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.Overview?Full-length EVERUNTM midsole for continuous cushioning throughout the run?BOA lacing system?ISOFIT dynamic upper?FORMFIT performance contoured footbed?Dual-density, ultra-grippy, PWRTRAC outsole for tractionSpecs?Shoe Category: Trail?Pronation: Neutral?Cushion: Responsive?Construction Type: Trail?Surface: Trail, Grass?Arch: Normal (Mid)?Offset: 4mm?Heel Stack Height: 22.5mm?Forefoot Stack Height: 18.5mm?Weight: 278 g.
