The present invention relates to a sock with a shock-absorbing pad, more specifically, sports socks, such as mountaineering socks, as well as soft polyurethane foam with excellent cushioning performance on the inner surface or the outer surface of the sole portion constituting a general sock or underpants The shock absorbing pad is made of material so that the vibration or impact force transmitted from the ground can be greatly alleviated when walking or running while wearing the shock absorbing pad to prevent damage to the ankle and knee joints. Is about socks.

In modern society, paved roads and even human walks are paved with cement blocks, asphalt, and concrete, so that the impact force generated when people walk or run is not absorbed and distributed to the ground. Since it is directly applied to the human body, it is easy to feel fatigue, and when walking or running for a long time, as the impact force is continuously applied to the human body, there is a problem that the joints of the ankle and knee are damaged.

In particular, in recent years, the spread of convenient means of transportation, such as automobiles, the nutritional intake is excessive, but the amount of exercise is largely insufficient, the ankle due to the impact that occurs when walking or running with a lot of overweight people who gain a lot of weight compared to normal weight The incidence of injury to joints and knee joints is also increasing day by day.

In addition, in the case of mountain climbing where long distance walking is required, or in sports events such as tennis or basketball, which require rapid movement and quickness, the joints of the ankles or knees may be used during leap and landing as well as during a momentary change of motion. It is known that excessive impact force is applied.

Accordingly, sports or leisure socks worn during sports activities such as tennis and basketball or mountaineering, weave the parts that are heavily impacted by the soles of the thick pile fabric, so that the impact can be alleviated somewhat. It has been proposed to use the sole material such as sneakers or hiking boots as a shock absorber such as rubber or the insole itself in direct contact with the sole using a shock absorbing member such as cork.

However, sneakers, hiking boots or thickly woven sports socks with such a shock-absorbing function may have some effect on short-distance walking in everyday life, but when walking long distances or climbing high and steep mountains In the case of strenuous athletics, there is a problem in that the weight-bearing impact force repeatedly delivered to the ankle and knee is not properly absorbed.

In addition, since the shoes or insoles having the above shock-absorbing function are useful only for outdoor activities, obesity or close to obesity must always protect the joints of the knee or ankle even when walking with daily indoor activities without shoes. The problem with overweight people is that their use is very limited.

The present invention is to solve such a conventional problem, the purpose is a soft polyurethane foam material with excellent cushioning performance on the inner surface or the outer surface of the sole portion constituting the general socks or socks, as well as sports socks such as hiking socks The new shock absorbing pad is designed to prevent the damage of the ankle and knee joint areas by greatly reducing vibration or impact force transmitted from the ground when walking or running while wearing it. To provide attached socks.

In order to achieve the above object, the present invention is made by weaving fibers, and the sock body is configured to wrap the foot in whole or in part; It is made of a predetermined thickness, and includes a shock absorbing pad attached to the inner surface or the outer surface of the sole portion constituting the sock body.

In the present invention, the shock absorbing pad is formed in a single shape having the same shape as the sole shape, and has a feature attached to the inner side or the outer side of the sole portion constituting the sock body.

The shock absorbing pad in the present invention has a feature attached to the inner surface or the outer surface of the sole portion constituting the sock body in a state separated into the front heel and heel.

In the present invention, the shock absorbing pad satisfies the rebound modulus of 1 to 15%, the compressive permanent strain of 1 to 10%, and the outgassing of 0.1 to 5%, and has a density of 0.3 to 1.0 g / cm 2 and thickness. It is a soft polyurethane foam having a sheet shape of 1 to 15 mm.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
