Shoes with flat soles.
It seems like flat shoes might be completely harmless. But doctors claim that these shoes can do a lot of harm to your health because the load on your foot will be uneven. There will be no shock absorption while walking. This will lead to your vessels increasing in size and losing their elasticity and the foot itself will become flat. It can lead to foot pain and back pain. Another unpleasant consequence is when the foot turns inside which leads to a deformation of knees and hips.
