Protects the growth plates that experience their first major growth spurt in children aged 5 to around 9 years old! If these close, it can hinder height growth, potentially resulting in growth below their natural potential! This is often seen in children from infancy engaging in sports with intense movements like karate, soccer, baseball, volleyball, and basketball, with heel pain being a common sign. While orthopedic doctors may recommend restricting exercise, support the heels even in daily life! This is a supporter designed for that purpose. Single units are available for 700 yen each.
