PRIMITIVE PERFORMANCE TECHNOLOGY

We’ve taken the shoe down to just the necessities. We’ve stripped away all the structure in a shoe and put it atop a sole that replicates the anatomy of the human foot. STEM’s Air Injection Rubber sole is specially formulated to mimic the physical properties of human skin.  It's the first sole with elasticity like our skin.  The STEM Primitive Performance sole delievers the experience that humankind has been missing.
