The Vibram Men's KSO Eco Shoes feature the same grip and durability found in other Vibram shoes but with the added bonus of a nearly petrol-free construction. They allow for superior traction on urban surfaces without the unnecessary weight and bulk found in typical walking and running shoes. The Ecostep Natural outsole is made primarily with natural ingredients, including a sustainable hemp upper material that is soft and form-fitting. Slip these on and you're ready for a run, a hike or a leisurely stroll around the neighborhood.
