The Biotrainer High is an evolution of the Biotrainer Low, inspired by classic high top basketball shoes and 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 are added, before cementing the leather outsole to the midsole using a natural, water-based glue. We refer to this process as a modified handsewn Goodyear construction—this method ensures all FEIT shoes can be resoled.
This FEIT low-pile English suede is vegetable-tanned and therefore breathes as in nature. It is non-irritant, soft to touch, ages richly over time, and biodegrades. The leather remains neutral regardless of the temperature, and does not retain sweat or odor, allowing FEIT shoes to be worn barefoot and get better with age.
This pair of FEIT shoes comes with an extra set of cork and buffalo leather insoles to assist with in-between sizing. The additional leather insoles 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.
