Problems solved by technology

And when people wear shoes, their forefoot is fixedly worn in a limited space in the shoe. Although the sole can absorb shock and the sole of the foot can rebound, when people are walking on the ground, due to the limited space in the shoe, the forefoot toes of the human body It cannot be extended smoothly, but can only be huddled together or stretched slightly, which is very limited, and the toe and toe of the front foot cannot be close to the natural barefoot state

Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, a shoe sole with freely extendable and retractable forefoot includes a shoe midsole 2 and a shoe outsole 1 stacked from top to bottom, and the shoe midsole 2 includes a midsole front block corresponding to the forefoot 21 and the rear block 22 of the midsole corresponding to the heel portion. The front block 21 of the midsole is a soft elastic pad;

[0025] Furthermore, the front palm of the shoe outsole 21 is gradually recessed from the outside to the inside to form an elastic stretching and retracting cavity 13, which can make the front palm of the shoe outsole 1 Extending freely outward or retracting inward, the elastically extending and retracting cavity 13 is a trumpet-shaped opening cavity structure.

[0026] Furthermore, the connection between the front midsole block 21 and the rear midsole block 22 is an inclined connection surface 23 .

[0027] Furthermore, the forefoot portion of the shoe outsole 1 also includes elas...

Embodiment 2

[0034] Such as image 3 and Figure 4 As shown, a shoe sole with freely extendable and retractable forefoot includes a shoe midsole 2 and a shoe outsole 1 stacked from top to bottom, and the shoe midsole 2 includes a midsole front block corresponding to the forefoot 21 and the rear block 22 of the midsole corresponding to the heel portion. The front block 21 of the midsole is a soft elastic pad;

[0035] Furthermore, the front palm of the shoe outsole 21 is gradually recessed from the outside to the inside to form an elastic stretching and retracting cavity 13, which can make the front palm of the shoe outsole 1 Extending freely outward or retracting inward, the elastically extending and retracting cavity 13 is a trumpet-shaped opening cavity structure.

[0036] Furthermore, the connection between the front midsole block 21 and the rear midsole block 22 is an inclined connection surface 23 .

[0037] Furthermore, the forefoot portion of the shoe outsole 1 also includes elas...

Abstract

A sole with a freely extensible and retractable front sole comprises a midsole and an outsole stacked from top to bottom; the midsole includes a midsole front piece corresponding to a front sole portion and a midsole rear piece corresponding to a heel portion, and the midsole front piece is a soft elastic pad; the front sole portion of the outsole is composed of elastic blocks distributed in mesh structure. The sole allows front toes of a user to naturally extend more sufficiently in walking or running, the front sole has enhanced grip, the ground touching process of the sole is approximate to touching by a bare sole, and it is more natural and comfortable to walk or run.

Description

technical field [0001] The invention relates to the field of foot care products, more specifically to a shoe with freely extending and retracting forefoot and its sole. Background technique [0002] Existing sports shoes include soles, uppers connected with soles and insoles placed on soles. Existing soles generally include outsoles and foam midsoles connected with outsoles. The outsoles are generally made of rubber materials. The above-mentioned foam midsole is generally a midsole made of a whole piece of EVA material or MD material. Sports shoes on the market are generally designed to enhance the cushioning and shock absorption of the sole, the rebound of the forefoot, and the grip and wear resistance of the sole. How to guide the forefoot toe of the human body to move outward more freely during walking The problem of extension and inward retraction has not been paid attention to and studied. [0003] When the human body walks or runs barefoot, after the toes of the fron...
