• The Biotrainer constructed from semi-cordovan leather. Historically, cordovan has been used only for luxury dress shoes. This leather is tanned using an extensive process. The hides must be tanned slowly, nourished with natural oils, and shaved.
  • The use of this highly luxurious and elevated skin allows the foot to breathe in a trainer that is 100% biological and handmade. Hand sewn from a single piece of leather, it features a padded tongue and raw edges, and is teamed with FEIT’s own natural gum sole. The sustainable, all-natural result is a luxury, running design.
  • Constructed from start to finish by one master craftsman, the Biotrainer is hand sewn from a single piece of English leather. This shoe is left on the last for ten days where light steam is used to tighten the leather ensuring superior shape and fit. It features a heel counter that has been molded from high-grade leather typically reserved for English dress shoes. The buffalo leather footbed provides padding, absorbs moisture, and breathes without retaining sweat or odor.
  • The unique sole of the FEIT Biotrainer is made of natural latex rubber from the milk of the hevea brasiliensis (rubber tree) plant. The milk is harvested by hand and poured into steel molds immersed in warm water. After one hour the sole is transferred into a cold water immersion bath that lasts up to 24 and helps to keep the rubber pores open while the material cures. After 24 hours of drying, the soles are re-immersed into cold water for one week until they are trimmed and inspected for imperfections. This two-week process results in a light and naturally flexible biodegradable sole that contains no plastic.
  • Individually handmade by skilled craftsman in Southern China.
