Description

Arch insole

The present invention relates to a shoe accessory, in particular to an arch insole.

A typical shoe usually includes an insole for the sole of the user. The insole is usually made of a soft material to provide a soft contact surface and improve user comfort.

However, because the soles of ordinary people are not completely flat, if the material of the insole is too soft, it is easy to cause the user's soles to tilt inward (that is, commonly known as the inner eight characters) or to the side when standing, walking or running because of insufficient support. Outer incline (that is, commonly known as the outer eight characters), over time, it will easily cause wear on the inside or outside of the sole, and will also affect the posture of the human body and cause soreness in the soles of the feet or other parts. If the material of the insole is too hard, although it can provide good support, it is easy to cause discomfort in the soles of the feet.

Therefore, the object of the present invention is to provide an arch insole with good support and comfort.

Therefore, the novel arch insole includes a bottom layer unit, a cladding layer unit, and a functional layer unit.

The bottom unit is made of plastic material and extends along a central axis. The bottom layer unit has a toe portion, a heel portion spaced from the toe portion along the central axis, and an arch portion located between the toe portion and the heel portion and on a side corresponding to the central axis. The cladding unit is disposed above the bottom unit along an axial direction perpendicular to the central axis. The functional layer unit is disposed between the bottom unit and the cladding unit, and includes a pair of front end portions corresponding to the toe portion, a pair of rear end portions corresponding to the heel portion and a material hardness greater than the front end portion, and a pair of Should be the arch of the foot and the material hardness is greater than the middle of the rear end.

The effect of the novel model is that by providing the rear end portion having a relatively large hardness and the front end portion having a relatively small hardness, the supporting force of the main stress point and the secondary stress point can be strengthened while considering comfort. And by setting the middle part made of a material with greater hardness, the arch insole can fit the sole of the foot with the arc of the arch, and reduce the amount of deformation when the force is applied, so as to avoid the arch due to the arch when walking. The curvature causes the sole of the foot to tilt.
