Men's AltraA(R) Wahweap :: From gym to crag to trailhead to dinner the Wahweap is ready to take you there. Named for a geological formation of the Grand Staircase-Escalante National Monument it features a comfortable and soft 75% hemp upper which is both functional and sustainable. To add to this already awesome shoe the MaxTrac outsole is "siped" for technical and multisurface traction and it features a climbing style wrapped toe for added function and durability.
