Heel insole

Abstract

This invention provides a heel insole that solves the problems of heel insoles that are prone to slipping and shifting, and lack stability, breathability, and comfort. [Solution] The heel insert comprises a support pad 1, a sponge layer 2, and heat dissipation holes 3. The support pad is integrally molded, with the rear side conforming closely to the heel and ankle, the upper side concave, and having reinforcing ribs (made of rubber) inside. Heat dissipation holes are provided on both sides to facilitate heat dissipation and removal. The sponge layer conforms closely to the bottom of the inner cavity of the support pad to protect the heel, and the innermost layer of the sponge layer is made of breathable cotton fabric, with a notch provided on the rear side of the support pad. This improves adhesion to the shoe cavity, solves slippage and displacement, improves wearing stability, breathability and heat dissipation, and comfort, and has high practical value.

Technical Field

[0004] , , , , ,

[0001] The present invention relates to the technical field of footwear, particularly to heel pads.

Background Art

[0002] Heel pads are used to fill the gap between the heel and the shoe, relieve the impact on the heel during walking, protect the heel, reduce foot fatigue, and improve the fit of the shoe, and are widely used in various shoes. Conventional heel pads often have a simple arc-shaped support structure, do not conform to the inclination of the heel in the shoe cavity, and have an insufficient position-fixing structure, so gaps are likely to occur in the front, back, left, and right in the shoe. In addition, due to the smooth contact surface and low friction force, slipping and displacement may occur during walking, resulting in a decrease in stability and possibly causing wear of the heel.

Summary of the Invention

[0005] The effects of this invention are as follows: - The integrated molding, angled cross-section, and reinforcing ribs ensure a tight, gap-free fit inside the shoe cavity, eliminating slippage and misalignment. - The rear rubber layer enhances friction and improves stability. - Double-sided heat dissipation holes + cotton inner layer provide excellent breathability and sweat wicking, reducing stuffiness. - The sponge layer improves cushioning and comfort.

[0007] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in Figures 1 to 3, the heel cushion has a support pad 1, a sponge layer 2, heat dissipation holes 3, and reinforcing ribs 4. The support pad 1 is integrally molded, with the rear side conforming closely to the heel and ankle, and the upper side formed in a concave shape. The cross-section of the support pad 1 is inclined to conform to the incline of the shoe cavity. A notch is provided on the rear side of the support pad 1 to improve the fit when worn. The heat dissipation holes 3 are symmetrically positioned on both the left and right sides of the support pad 1, allowing heat and sweat to be released through air circulation, and also facilitating the insertion of fingers for easy removal. The reinforcing rib 4 is integrally molded with the support pad 1 from rubber material, pushing the support pad 1 outward and making it fit snugly against the inside of the shoe. The sponge layer 2 is made of high-rebound sponge and is adhesively fixed to the bottom of the inner cavity of the support pad 1 to mitigate heel impact. The innermost layer of the sponge layer 2 is covered with breathable cotton fabric, which is soft to the touch, absorbs sweat, and ensures breathability. A rubber layer is attached to the rear outer surface of the support pad 1 to increase friction with the inner surface of the shoe and prevent slipping and shifting while walking.

[0008] Manufacturing method (example) 1. The support pad 1, including the reinforcing rib 4, is integrally injection molded. 2. Apply hot melt adhesive to the outer surface of sponge layer 2 and adhere it to the bottom of the lumen of support pad 1. 3. Adhere the rubber layer to the rear outer surface of support pad 1 and press it into place. 4. Open ventilation holes 3 on both sides of the support pad 1 and remove any burrs.

[0009] How to use Attach the half-insole to the heel of the shoe. The rubber layer on the rear of the support pad 1 adheres tightly to the inside of the shoe, and the reinforcing rib 4 protrudes outward to eliminate any gaps. The sponge layer 2 softly contacts the heel and absorbs impact. The ventilation holes 3 ensure breathability and prevent stuffiness. To remove, simply insert your finger into the ventilation holes 3 and pull it out. Although embodiments of the present invention have been described above, the present invention is not limited to the above-described forms, and various modifications are possible within the scope of the claims.
