We here at Lems Shoes don't always wear shoes, but when we do we choose the Primal2. If lightweight (6.9oz), flexible, breathable, foot-shaped, and flat are all characteristics that you look for in footwear, than look no further than this shoe. The Primal2 is assembled using a no-sewn construction, which allows the shoe to comfortably form to the natural shape of your foot. Lightweight microsuede and open-weave mesh, allow your foot increased airflow and better breathability. The low-profile 8.0mm LemsRubber sole brings you closer to the ground for a more natural stride. Our LemsLast design, with its natural foot shape, provides you with that Feelgood Fit that we pride ourselves on. So whether at work, walking the dog, or running errands, the Primal2 is certainly the 'go to shoe' for you.
