As a barefoot/minimalist runner, I run over 85% of my miles barefoot. I am very particular about any “shoes” that I wear for a run. In extreme weather (hot or cold), I will run in huaraches. For very rugged trails or gravel levees I might wear Vibram KSOs. The Sockwa G2 offers something in-between.
G2 is the new and improved Amphibian, with larger toe box, and more minimal design. The 1.2 mm thick TPU Sole is sensitive to subtleties in temperature and texture changes on concrete, wood, grass, sand, sea-shells, gravel, etc. The G3 is the 2012 version of the G2.
