Support insole for shoes

Abstract

An support insole includes a middle medium sandwiched between flexible upper and lower layers, wherein upper layer has a forefoot region with a metatarse protrusion that projects upward from an upper surface of the upper layer to a certain height, a midfoot region with inner and outer arch sides, wherein the inner arch side has an inner arch protrusion that projects upwardly from the upper surface to a certain height and wherein the outer arch side has a plurality of outer arch protrusions that project upwardly from the upper surface to a certain height, a hindfoot region with a heel support protrusion that projects upwardly from the upper surface to a certain height, wherein the top face is dented inwardly so as to form a concave recess such that the support insole is ergonomically designed to provide comfort for a wearer.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates generally to an insole, and more particularly to a support insole for shoes which is ergonomically designed in such a manner to provide extra comfort to reduce fatigue of foot, thereby enabling a person to maintain a normal walking condition.2. The Prior Arts[0002]When we are walking, we are putting 0.8-1.2 times of our body weight on a single foot in addition to the counterforce from the ground. The counterforce of the ground usually causes problems in our ankles, knees, skeleton or other body parts and in the long time, may result in injury to our foot, especially knees and ankles. To avoid this, it is best to put a support insole in our shoes to absorb the stress or shock.[0003]A conventional support insole is fabricated from leathers and simply provides support to our feet. In other words, the conventional support insole is weak in shock absorption. Another support insole fabricated from elas...

AI Technical Summary

Benefits of technology

The present invention provides a support insole that is ergonomically constructed, has better impact resistance, and provides comfortable feeling during walking. The insole includes a flexible upper layer, a middle medium, and a flexible lower layer. The upper layer has a forefoot region, midfoot region, and hindfoot region with different protrusions for better cushioning and impact resistance. The middle medium securely fixes the upper and lower layers together. The insole provides a balance cushioning support to the entire sole of the foot and also supports the forefoot in a greater area and volume during walking.

Problems solved by technology

The counterforce of the ground usually causes problems in our ankles, knees, skeleton or other body parts and in the long time, may result in injury to our foot, especially knees and ankles.

Owing to damping characteristics of the elastic support insole and due to each person requires energy during walking, the muscles of the foot still may get fatigue.

In addition, it is noted that the elastic support insole is too soft and is weak in resistance against the impact of the ground.

The conventional support insole fails to provide cushioning effect to the arch portion of the foot, hence causing fatigue to the walking foot.

Another drawback of the conventional support insole resides in that the hindfoot portion is generally flat and therefore fails to provide cushioning effect the heel of the foot, thereby causing discomfort the wearing person.
