Description

Outsole with improved fit}

The present invention relates to an outsole with improved comfort.

In general, shoes such as shoes are composed of an upper that covers the instep and an outsole that is coupled to the lower part of the upper and supported on the ground.

Here, the outsole is the part that directly contacts the ground, allowing the shoe to stand firmly without slipping, and is made of various materials to increase durability and friction resistance.

As such, the outsole is composed of a pad portion coupled to the lower part of the upper to support the sole of the user's foot, and a heel portion coupled to the pad portion to support the user's heel.

However, unlike the outsole for sneakers, which is made of elastic foam material to reduce weight, the outsole applied to shoes, etc., is made by compressing rubber or urethane material, so it is harder and weighs more than the outsole for sneakers.

In particular, the heel part that supports the user's heel is manufactured with a higher thickness than the pad part and has higher hardness, causing pain in the user's heel and arch when the user wears the shoe for a long time. There was this.

(223) can be raised by pressurizing.

The support ball 225 is rotatably coupled to the ball support holder 223 and can support the arch of the foot by supporting the lower surface of the sole body 1.

Figure 6 is a plan view schematically showing a state in which the arch support point variable part is installed on the heel body part according to an embodiment of the present invention.

Referring to Figure 6, the outsole 1000 may further include an arch support point variable portion 5.

The arch support point variable part 5 is accommodated in the heel body part 21, is coupled to the arch support part 22, and is rotated by the manipulation tool (T) to transport the arch support part 22 in the left and right directions. there is.

The arch support point variable part 5 may include a body support 51, a support transfer unit 52, and an opening/closing cap 53.

The body support 51 is accommodated inside the support body 222 to support the support body 222, and is coupled to the support transfer unit 52 to support the support body 222 by the support transfer unit 52. Can be transported in the left and right directions. For example, the body support 51 may be made of a material having higher hardness than the support body 222.
