Besides the running speed, there are other criteria that can be used to divide the different categories A, B and C.
BIOM A is the shoe for the "serious runner", the professional to semi-professional runner. Who trains hard and tries to push themselves to the limit. The "serious runner" tries to find self affirmations and extremities, or self awareness whilst running.
BIOM B focuses on the "fitness runner", whose main motivation is to better their bodily condition. The "fitness runner" often trains for other sports and commonly likes to move. These runners like to have a special connection with nature.
BIOM C is the shoe for the "occasional runner", or the "opportunity runner". Most noticeable about these runners is that their wish is to better their bodily condition, fitness and a healthily way of living.
