Abstract

The insole described within uses a multiplicity of nodules of varying diameters and heights to provide the requisite level of flexibility, support, and stimulation to the various regions of the foot. These advantages are created while maintaining a low thickness, thereby allowing the insole to fit within a shoe without creating discomfort. Gradients of pressure that generate variations in the laminar flow of the foot bed lead to better circulation and perfusion of the capillary foot bed of the foot transection irrigation, allowing for better circulation and venous return.

Abstract

The shoe herein, in the form of a sandal, uses a combination of a midsole of varying thickness and nodules of varying diameters and heights to provide the requisite level of flexibility, support, and stimulation to the various regions of the foot. The walking action of the user creates waves of pressure across the foot, enhanced by the nodules, thereby increasing blood flow. Gradients of pressure that generate variations in the laminar flow of the foot bed lead to better circulation and perfusion of the capillary foot bed of the foot transection irrigation, allowing for better circulation and venous return.
