Description

  The present invention relates to a shoe insole that softens the impact of a sole or toe in a shoe by walking, and more particularly to a shock absorbing / slip proof insole of a shoe that can be applied to shoes of a size slightly larger than usual.

  In general, an insole for footwear prevents shoe rubs by filling the gap between the foot and the foot or providing cushioning (cushioning) when the inner shape of the footwear such as shoes and the foot of the wearer are incompatible. Such an insole for footwear is made of a flat elastic sheet having a constant thickness.

  In order to prevent foot pain due to obstacles such as hallux valgus and flat feet, and to eliminate other comfort problems, such insoles have been improved, "from the thumb base of the insole to its front and little finger base The front part of the collar part is cut off and dropped, and a through hole is formed in the collar part or the front side of the collar part is cut in the left-right direction so as to be stepped down, and on the upper side of the insole, there is a cushioning elastic sheet. An insole-shaped insole formed with a body is known (Patent Document 1).

  In addition, many shoes are made so that the thumb base and the little finger base are tightened, so that the foot that takes the whole weight is put into a mold. For this reason, when wearing shoes that are slightly larger than usual, your feet may slip forward in your shoes and your toes will hit, and your heels will loosen and become easy to remove, and your feet may hurt or become difficult to walk. It is often experienced.

  A shoe insole is known in which an elastic polymer sheet excellent in anti-slip property is provided on a common insole so as to obtain a good comfort of the shoe during walking (Patent Document 2). .

  By the way, it is said that only shoes are required to have accuracy in millimeters among things worn by people as clothing, especially for matching shoes to fit shoes with painful or disabled feet. Delicate adjustment is required.

  However, compared to shoes whose size does not change, the size of a person's feet changes every moment depending on various conditions. For example, if the same posture is maintained during long standing work or desk work, lack of exercise, sleep Depending on the season, people's feet are swollen and large when there is a shortage, cooling due to air conditioning and stress, etc., and the feet tend to be large in summer when the temperature and humidity are high, and conversely the feet are small in winter. There is also a change in size.

  Therefore, it is desired to be able to adjust so as to eliminate or reduce foot pain during walking according to individual differences of people wearing shoes and various wearing conditions, and to make such adjustment as easy as possible. ing.

  However, an insole-shaped insole (see Patent Document 1), which is made of the above-described cushioning elastic sheet and is cut off by cutting the front side of the buttocks in the left-right direction, Since the contact pressure of the thumb and little finger is reduced, the shoe with the insole attached for a long time in such a state that the thumb and little finger move freely in the shoe and prevents the load on the toe from being firmly supported. When you walk using it, your entire foot gets tired or uncomfortable.

  In addition, in order to reduce such problems, when a slip-proof resin sheet as described in Patent Document 2 is used as an insole, the breathability in the shoes deteriorates and the soles are stuffy in summer. There is a problem.

  In addition, the non-slip resin sheet is fixed to the insole surface by bonding or sewing and cannot be easily removed, so that the contact pressure of the big toe and little finger on the inside of the shoe is appropriate when walking. It was not easy to adjust according to individual differences.

  Therefore, the object of the present invention is to solve the above-mentioned problems, and the inside of the shoe with the insole of the shoe is comfortable to wear without being steamed for a long time, and the toe and little finger do not play in the shoe during walking. Shoe cushioning and anti-slip properties in the shoe that can support the weight firmly and can reduce or eliminate foot pain by properly adjusting the contact pressure between the inside of the shoe and the toes according to individual differences It is to make a good insole.

  In order to solve the above problems, in the present invention, a shoe that can be established by quantification by a clinical test for eliminating foot pain and an insole used for the shoe are completed (“clinical test / quantification / establishment possible”). Completion of shoes and insole ”), the surface of the sheet-like substrate is provided with an anti-slip sheet provided with a number of anti-slip protrusions made of elastic resin or rubber with air-permeable gaps, and the back side of this anti-slip sheet is impacted A shoe comprising an insole that can be peeled off and integrated with a cushioning insole body, and a portion of the anti-slip sheet that can press the main portion of the foot in the shoe is provided so as to be cut off. This is a cushioning / slip-proof insole.

The shoe cushion / slip proof insole of the present invention configured as described above has both air permeability and anti-slip property by anti-slip protrusions fixed on the surface of the anti-slip sheet with a large number of air permeable gaps. When walking, the toes and little toes do not slide or move inside the shoes, and the load applied to these toes is firmly supported, so the transmission efficiency of the foot force to the shoes is improved. Even if you use shoes with insoles for a long time, your feet will not get tired and your comfort will be improved.
In addition, when the sheet-like base material of the anti-slip sheet is a breathable knitted fabric, the breathability is further improved.

Further, the cushioning / slip-proof insole of the shoe of the present invention can be peeled and integrated with the back surface of the slip-proof sheet placed on the impact cushioning insole main body, and the essential part of the foot is placed inside the shoe. Since a part of the anti-slip sheet that may be compressed is provided in a material or thickness that can be cut out with a blade or the like, a part of the anti-slip sheet is manually cut out, and the main body of the anti-slip sheet May be re-adhered with an adhesive or a double-sided adhesive tape, etc., which is appropriately stacked on the insole body.
In this way, the contact pressure from the shoe against the main part of the foot, such as the big toe and little finger inside the shoe during walking, can be reduced, so that shoe rubbing and pressure pain can be reduced or prevented.

As described above, the back surface of the non-slip sheet and the insole body have an adhesive layer such as a double-sided pressure-sensitive adhesive sheet so that the back surface of the anti-slip sheet can be integrated and peeled over the insole body with impact buffering. It is preferable to form a shock-proof / slip-proof insole for shoes that are integrally provided in a state where peeling and re-adhesion are possible.
In other words, the cushioning / slip-proof insole of the shoe constructed in this way is once peeled off from the insole body against the adhesive force of the anti-slip sheet, and the foot in the shoe wearing the shoe insole is essential. After cutting out a part of the anti-slip sheet that may squeeze the part with a knife such as a scissors or a cutter knife, the adhesive layer re-adheres to the insole body. The contact pressure of the little finger can be reduced, and can be easily adjusted as appropriate to an appropriate state according to individual differences and foot pain symptoms.

  In addition, in order to ensure that the anti-slip sheet is peeled off from the insole body and the main part can be easily cut out, the surface of the anti-slip sheet corresponding to the main part of the foot is semi-finished. It is preferable to adopt a cut line or a cut mark line.

  In particular, when the foot cushion or anti-slip insole of the above structure is used when the main part of the foot is the thumb base or the little finger base, or both, the required part of the anti-slip sheet can be easily cut off. The contact pressure of the inner foot can be easily adjusted to an appropriate state according to individual differences.

  This invention uses an anti-slip sheet in which a number of anti-slip projections are fixed on the surface of a sheet-like base material with air-permeable gaps, and this is overlaid on an insole body with impact cushioning so that it can be peeled off integrally. Since the shoe has a cushioning / slip-proof insole that can be cut off the portion of the shoe that may press the main part of the foot in the shoe, sweat does not accumulate on the surface of the insole. It is comfortable to wear without stuffiness, and the toes and little toes do not slide in the shoes and do not move when walking, so that it can support the weight firmly, and the inner bottom of the shoe contacts the toes and little toes. Since the pressure can be reduced in an appropriate state according to individual differences, there is an advantage that it becomes a cushioning / slip-proof insole for shoes that can surely reduce or eliminate foot pain.
