High heel alter posture and increase pressure on the ball of the foot. Repeated wear is already known to strain the hips, knees and thighs as well as increasing the risk of conditions such as osteoarthritis, hammer toe, back problems, bunions and corns. To investigate the differentiation of foot posture parameters during wearing high heel in normal female subjects. Thirty normal female subjects their age ranged from 18-25 years old; they were vounteers from public desouq hospital. Thirty normal female subjects already wearing high heel, or at least 8 weeks, height of heel was 2 inch or 5 cm. Each subject was asked to stand on the lateral step of the X-ray device side by side to the vertical table, then the subject was asked to bear his body weight on the foot to be examined while the other foot and leg were maintained behind the examined foot. Four angles were measured (Talonavicular coverage angle, meary,s angle, calcaneal pitch and lateral talocalcaneal angle). There were three angles were mostly affected and had marked flat foot as follows; meary{u2019}s angle [30 / 30 (100%)], calcaneal pitch angle [29 / 30 (96.7%)] and finally talonavicular [21 / 30 (70%)]. So, the degree of angle affection in females were ranged 21 (70%) to 29 (96.7%). wearing of high heel for long period of time might cause ankle mechanical insufficiencies include pathologic laxity, impaired arthrokinematics, mechanical, functional instability and weakness of muscle control foot arches, which might cause flat foot
