Insole Pro for flat feet, men's, 1 pair (size L (2 pieces))

●The world's first "trouble-specific insole" based on the theory of insole that uses one's own body weight as a corrective force. ●"Flat feet" is a condition that occurs when the "medial longitudinal arch," one of the three arches necessary for efficient walking, collapses. Insole Pro "Flat Foot Countermeasures" restores the weakened "medial longitudinal arch" to a normal state and supports comfortable walking. ●Maintains the arch function that absorbs shock when walking, relieving fatigue in the soles of the feet. ●For hygiene inside the shoe, the surface material has been treated with antibacterial and deodorizing agents.
