INSOLE IMPROVEMENT
An insole improvement (100) is described which has, in the portion where the transverse arch of the foot is placed, an area provided with a concave surface (10) that fits the region of the user's foot arch so as to prevent the foot from slipping forward from the shoe, which generates pressure on the forefoot, in addition to providing support to the heel.
The present invention describes an insole improvement.
More specifically, it concerns an insole suitable for being adapted to high-heel shoes, presenting, in the region where the foot arch is placed, a salience that fits this anatomic area, preventing the foot from slipping forward.
BACKGROUND OF THE INVENTIONHigh heels are a symbol of female elegance but cause discomfort with foot pain.
High heels decrease the muscle pump role of the leg muscles and may, with continued use, lead to venous hypertension in the lower limbs and varicosis.
With high heels, the axis of the body changes, forcing the foot forward.
The foot tilts down, straining the forefoot, which may cause injury to the metatarsal head.
In addition, the use of high heels strains the calf and may cause tendinitis and lesions to the muscles of the lumbar region, leading to back pain and knee problems.
The prior art describes some insoles for high-heel shoes that primarily present a buffering region that alleviates the pressure on the plantar support area of the feet.
However, even with insoles that alleviate the pressure on the plantar support area, the region of the foot arch is strained downwards during the use of high heels, causing discomfort.
Therefore, the object of the present invention comprises an insole improvement that has a salient portion in the area where the foot arch is placed, providing stability to the foot, preventing it from slipping forward, avoiding pressure on the forefoot and on the plantar support area, and favoring the maintenance of body posture.
SUMMARYThe invention is characterized by an insole improvement suitable for use with high-heel shoes, preventing the foot to slip forward as a result of the slant caused by the high heels.
The invention is characterized by an insole improvement that fills the area that supports the foot arch, preventing the foot from slipping forward out of the shoes and, consequently, eliminating the pressure on the plantar support area.
The invention is characterized by an insole improvement that distributes the body weight throughout the insole.
The invention is characterized by an insole improvement that fits the measurements of the foot arch.
The insole improvement, the object of the present invention, comprises an insole (100) suitable for high-heel shoes that has, in the region where the transverse arch of the foot is placed, an area provided with a concave surface (10).
The concave surface fits the region of the user's foot arch so as to prevent the foot from slipping forward from the shoe, which generates pressure on the forefoot and discomfort, in addition to providing support to the heel.
The insole can be adapted to the internal portion of the shoe or the fixed insole of the show can have a concave relief in the area where the transverse arch is placed, allowing the foot to be put on the ground comfortably.
The region where the transverse arch of the foot is placed has a concave area (10) that is between 1 cm and 4 cm high.
