The low shoe contains a sole, a soft top connected to the sole, hard frame parts connected to the soft top, an amplifier connected to the soft top and hard frame parts, and wrapping around the heel-beam part and partially the heel part of the foot and containing holes, and elastic elements of two types, the first of which passes through the holes, and the second connects the edges of the amplifier in the instep and beam part of the foot.

Also low shoes contains an insert orthopedic insole. The low shoe is made with an upper made of breathable 3D knitted jersey. For lining in a low shoe, a hygroscopic 3D bulk shoe lining material is used, for example, mesh. A removable orthopedic insole and structural elements of the low shoe make it possible to adjust the space inside the shoe, thereby having a therapeutic and prophylactic effect on the foot.

Rigid frame parts are a heel and toe cap made of leather. Elastic elements are shoe woven elastic in the form of a strong highly elastic woven tape. Shoe woven elastic has such qualities as elasticity, strength, resistance to deformation, UV rays, and moisture. Shoe woven elastic is produced by the method of complex weaving of high-strength threads (polyester + latex in a ratio of 70/30). Shoe woven elastic has a more rigid texture, the surface without loops is smooth and dense. Shoe woven elastic is used as an element of decor, for adjusting details when sewing shoes.

However, the design of low shoes does not have protective properties, which makes them almost impossible to wear for people of working specialties.

From the patent document for industrial design No. 103928 dated 06/21/2017, boots with a knitted top of three-dimensional knitting by fusing parts in the toe heel parts, on a two-layer sole made of polyurethane and thermopolyurethane of the molded fastening method, containing a flat insole, are known. With pathologies of the musculoskeletal system (flat feet), such shoes are not applicable. In addition, this design is very difficult to manufacture and does not provide the necessary protective properties.

From the source of information: https://getsiz.ru/tekhnologiya-3d-vyazki-v-proizvodstve-specialnoj-obuvi.html, the use of 3D knitting technology in the production of special footwear, namely, protective footwear of the Space series using the technology 3D knit upper. The new technology of 3D-knitting of the textile blank of the upper opens up endless possibilities for any design and individual execution of shoes. Ready-made shoe models have the following advantages: high breathability; a minimum of seams increases comfort when worn; reliable fastening of the molded sole - more than 90 N / cm²; unsurpassed lightness - knitted material is 2.5-3 times lighter than natural leather; high resistance to abrasion, stretching and tearing; shoes can be washed at temperatures up to +40°C; hygiene and comfort.

However, these shoes cannot be used in diseases of the musculoskeletal system, in particular, for their prevention and to reduce the risk of developing diseases.

From the source https://okean.shop/products/botinki-rabochie-ultima/ Safety Jogger Ultima S3 work boots are known, which are the top solution as safety shoes for various types of work. The Ultima model combines stylish appearance and maximum protective properties. The upper material is genuine grained leather 2.6 mm, the thickness and type of leather has a positive effect on wear resistance and provides protection from water. Composite toe cap and SJ Flex anti-puncture insole provide maximum protection against injury in the workplace. The Coolmax lining provides additional cooling for the feet during intensive work. The two-layer sole made of polyurethane and nitrile is not afraid of high temperatures, which makes it possible to use Safety Jogger Ultima S3 work boots for road construction. The Safety Jogger Ultima is metal free, which affects the final weight of the work boots.

However, these shoes cannot be used for diseases of the musculoskeletal system, in particular, for their prevention and to reduce the risk of developing diseases.
