The Biotrainer Low is a luxurious and sustainable running-inspired design, featuring a heel counter molded from high-grade leather typically reserved for high-end men's dress shoes. The unique sole of the FEIT Biotrainer is made of natural latex rubber from the milk of the hevea brasiliensis (rubber tree) plant.
All FEIT shoes are made from start to finish by one master craftsman. The one-piece upper is sewn by hand directly to the midsole. A cork footbed and a bamboo shank stabilizer is added, then the leather outsole is cemented to the midsole using a natural, water-based glue. We refer to this process as a modified hand-sewn Goodyear construction.
Goodyear construction ensures all FEIT shoes can be resoled.
Each pair of FEIT shoes comes with an extra set cork and buffalo leather insoles to assist with in-between sizing. The additional leather insole can be used alone, or the cork can be inserted underneath the leather for extra padding. If you are between sizes, you can either size up and use the included insoles, or size down and use no additional insoles.
