The invention relates to medicine, namely to orthopedics. It serves for preventing human flatfoot and massage active zones situated on the feet.Known model to solve the problem of flat feet: customized orthotics (utility model patent №59968), orthopedic insole (Patent of the Russian Federation on the PM №32997, 2003 Kl A61F 2/60..)When using orthopedic insoles often have to follow the arch of the foot insoles for timely correction. Insoles correct only flat, not to speak of a natural foot massage. After all, in the boot rigidly fixed foot, and on the specific point of it constantly for a long time are the same stimuli.Proposed consideration simulator for prevention of flatfoot, massage and effects on the active areas stop human has one feature: warmed to + 30 ° C, using a heating system, sand and gravel under the action of human gravity, walking act on the foot based on their individual characteristics. Rough sand surface and movable simulator for each step will contribute human anatomically correct formation of transverse and longitudinal arches of the foot, and affects the pebbled surface active zones brake as acupressure. Each person simply walking barefoot on the sand 20 minutes a day doing simple exercises (walking on the inside and on the outside of the foot, walking on his toes and heels, simple steps). In addition to the sand filling, part of the floor space is filled with pebbles (sea or river), which will also warm up to + 30 ° C. With the help of pebble is a natural massage active zones on the feet of man.The heating pipes circulates liquid, low-temperature heat medium (water) at + 40 ° C from the central heating system or a hot water boiler.Summary of the utility model is illustrated by drawings, which illustrate the proposed consideration simulator.1 shows a sectional simulator. Figure 2 depicts the simulator (top view) to backfill sand and pebbles.According to Figure 1 on a concrete floor 1 is laid flat the entire area of the heat insulating material
