1. The shoe enables, best as possible, a natural feel of the ground with a minimal sole
2. It has a zero heel drop, meaning the rearfoot and forefoot is the same height, allowing the ball of the foot and heel to bear an equal load in weightbearing
3. It does not have a toe spring (the end of the shoe doesn't curve upwards). This is important because a toe spring allows the metatarsophalangeal joints and toes to be a passive component in the gait cycle. A toe spring essentially prevents the toes from gripping the ground and the first metatarsophalangeal joint from pushing off; prohibiting the natural function of the foot.
4. It has not only a wide forefoot, but a wide TOE BOX. This is ideal to prevent the wedging of the 1st and 5th digits inwards, which can contribute to bunion and tailor's bunion deformities as well as neuromas.
Like I mentioned before, many minimalist running shoes have applied these concepts, but Stem footwear applies these for regular daily use shoes. These are the type of shoes we should be wearing on a daily basis to make full use of the natural function of our feet.
Before you spring in to the stems, as I fully recommend, you must realize that they are a shoe that will change your gait and function drastically if you havent already been transitioning to barefoot and minimalist shoewear. Transition exercises focusing on stretching your achilles tendon and strengthening your instrinsic foot musculature as well as the muscles in your lower leg are essential to prevent injury. Please come see me if you are interested in making the minimalist/barefoot transition and finding out what your feet are capable of!
