Quantitative evaluation of load distribution disorders in foot zones under various biomechanical conditions was made. 14 women (7 had normal feet, 7 suffered from transverse platypodia) were examined. All of them were examined during standing and walking in footwear without heels, in footwear with 60–70 mm heels, in footwear 80–90 mm heels. Control group consisted of 29 clinically healthy patients aged 19–49 years. Feet pressure alterations in the view of 2–3 metatarsal bones on touch insoles was estimated by computer-assisted «F-scan» apparatus. Walking on 60–70 mm heels in the view of 2–3 metatarsal bones heads caused the increase of pressure while one-support period of step cycle in patients with transverse platypodia of 2 stage; walking on 80–90 mm heels resulted in significantly increased norm indices. The heel optimal height should not exceed 20–40 mm. In its height more than 60 mm distress manifestations both in the foot and in the proximal segments were developed.
