Walking Foot Strikes #60392245
Description
Illustration of how a walking foot strikes the ground. Shown are three stages: 1) before the foot strikes the ground, the rounded arch is poised like a steel spring (left); 2) as the foot hits the ground, the impact flattens the arch and the Achilles tendon stretches; and 3) the arch springs back to shape and the Achilles tendon contracts (right).
