Insert in the shoes is a removable insole, which performs a number of functions. In particular: a daily wearing comfort, relief of pain in the foot and joint pain arthritis, excessive stress, injuries and other problems; Orthopedic correction, reducing odor, enhance athletic performance or even increased growth the owner of shoes or correction of leg length difference. Corrective inserts in footwear is often called the Orthopedic. Removable insoles can contain native support (calculation) for the longitudinal Arch of the foot.
In this way the insole is the lower inner detail of the shoe that is directly under the foot, under the insole (also known as lining). The insole is attached to the edge of the upper part of the shoe tightening, which is wrapped around the shoe pads during the boot operation closing delay. Are made usually of cellulose paper or synthetic non-woven material. Often, the shoes have removable or interchangeable insoles. The additional depreciation usually serves as a convenience when worn (to control forms, moisture and odor) footwear or apply for medical reasons (to help cope with the natural shape of the foot defects or for fixing the foot when standing or walking).
As already mentioned, the insoles provide extra cushioning or corrective effect. Based on the types of abnormalities in the foot, you can identify the purpose of correctional intervention (ortezirovaniâ):
Accordingly, the insole can be divided on:
On the method of exposure of the human locomotor Orthotics can be divided into two groups:
Correcting or changing the position of the individual – offload parts of the foot.
Sensory-motor is affecting the nerve roots at plantarnoj surface of the foot.
Sensory-motor orthopedic insoles are a relatively new area, their distinctive feature is the presence of hard material, not under the Arch of the foot, and projected “active pixels” on a plantarnoj surface. Such insoles are encouraged to nominate high toned muscles of the lower limbs (including effects of cerebral palsy), scoliosis and other diseases. These products should be regarded as a phase of conservative treatment. Critical to the effectiveness of insole has competent implementation of doctor’s recommendations.
materials for manufacturing of Orthopedic insoles
In the manufacture of individual orthopedic insoles used natural materials – leather, Cork, as well as modern high-tech materials-EVA, Veldona, Microliner and others who give strength to absorb insoles excess moisture, have good cushion, non-allergenic properties.
production of orthotic insoles
: technology of making individual insoles
For effective correction of dysfunction or pathology of the foot requires a complex set of different Genesis, an integral part of which is the use of orthotic insoles (orthoses). Corrective insoles and reinforcing cushion should have properties to fix existing distortions and deviations from the physiological status of the foot. In addition to the required strength, wear resistance, damping, modern manufacturers are trying to make them more orthoses comfortable, improve their hygienic properties. To meet these challenges, should ensure that:
sufficient ventilation and high moisture capacity of insoles,
making antiseptic properties
This is accomplished using the soft porous materials, special layers of impregnated activated carbon, antimicrobial compounds and the internal surfaces of the silver nanolayers insoles. Important some of the insoles is washing, disinfectant formulations and processing no shrinkage while drying. Currently known and widely used, many generic orthotic insole, let out by the industry. However, the most optimal are the manufacturing methods of individual orthopedic insoles, which allow to take into account all peculiarities of the foot of the patient: degree of reduction of inner and outer longitudinal arches, elasticity, amount of pronation of the heel bone. Development of constructions and the sequence of technological operations is based on biometric and biomechanical Diagnostics based on geometric parameters characterizing the pathology of the foot (the geometrical dimensions of the height, area, contact the main anchor Plantar parts of soles, heel position, trajectory of walking). Orthotics manufacturing techniques can be divided into 3 main classes:
Products made by casting (products of mass production).
Product made in molds method of molding under individual mould or forming pads (low volume or individual products).
Products manufactured on CNC on mathematical model derived from a scan of the foot (individual parts).
