Wooden clog with rubber sole and leather strap, with a topography that adapts perfectly to the arch of the foot. The anteroposterior axis of the sole applies an 8-degree backward slope to the foot. The heel sits lower than the toes. The patented slope of the upper face, in contact with the arch of the foot, shifts the body's centre of gravity slightly backwards. The spine undergoes less stress, allowing the abnormally stressed erector spinae muscles to stretch, which can relax, engaged in this rebalancing by the retroversion of the pelvis. The surface of the hoof is specially shaped so that the bottom of the foot assumes a correct position. With each step, this increased alternation of contraction/relaxation helps to intensify the pump effect in the calves, thus increasing blood and lymphatic flow in the lower extremities. Cellular tissues are better drained, better irrigated. In blue colour.
