>>1212867It has nothing to do with genetics, flat feet being genetic is a meme. Everyone has a hallicus longus, flexor digitorum and all the foot muscles required to form an arch, poor biomechanics is what ruins people's body. Post your legs and feet faggot lets see em, I can tell if you are a leglet just by analyzing your posture
>>1212859if you want to be a minimalist then don't use anything man has created to benefit himself physiologically. Arches can be developed naturally by many means, but giving your body a structural support that forces your body into physiological correctness will be better than not doing so and not reaping the benefits of proper biomechanics.
>>1212788far too complex to diagnose but the fat that you are constantly on uneven ground makes a big difference in developing foot/calve muscles. If you are traversing inclines with natural biomechanics you'd be developing proper strength in such areas even if barefoot.
