FUNCTIONAL FIT RUNNING INSOLES Insoles Insoles Size: S (23.5cm) Color: Yellow Price: 4,290 yen (tax included) Purchased from STEP, a specialty track and field store. My child used them for half a year in club activities. 【Innovative insoles born from biomechanics research】 These insoles aim to reduce foot strain and improve performance by keeping the foot's skeletal structure in the correct state. They were developed from the perspective that it is necessary to push up the position of the bones existing between the two types of joints (Chopart's joint / Lisfranc joint) in order to correctly maintain the three arches of the foot (outer, inner, and transverse). Compared to other commercially available insoles, these insoles have a sensation of pushing up the heel area. By exercising with the correct arches, improvement in athletic ability can be expected. In addition, the running type has firm arch support, so it is recommended to use them in running shoes, especially those designed for long, slow, and safe running. Expected effects ・Improved athletic ability Correcting the 3 arches (outer, inner, and transverse) transmits power without waste and improves athletic ability. ・Increased muscle pump action The muscle pump action of the lower limb veins increases, blood flow improves, and fatigue is reduced. ・Improved fit The foot and shoes fit together, eliminating movement loss. ・Shock absorption The special shape and cushioning distribute body pressure and absorb the impact on the heel. ・Antibacterial/deodorant effect Controls the growth of causative bacteria through antibacterial effects, suppressing the generation of odors. ・Reduced foot problems Prevention and improvement of shin splints and runner's knee can be expected. ・Prevention of hallux valgus Prevention and improvement of flat feet, high arches, and hallux valgus can be expected. ・Correction of X-legs/O-legs There is an effect of correcting X-legs and O-legs by returning the inclination of the tibia.
