Walking Teacher Insoles Size: M (23.0cm - 23.5cm) When shipping, the insoles will be removed from the box, and the box will be folded for shipping. Authentic product developed with the theme of "pelvis," the key to health and beauty, using an academic approach. Walking correction insoles co-developed with Hiroshima University. Thin insoles that you can simply place in your favorite shoes. The special gel lines naturally guide the "weight transfer of the sole" from the heel → the outside of the arch → between the big toe and index finger. The 6° angled gel material at the toes encourages grip of the toes. It unconsciously guides ideal weight transfer and toe grip, achieving a firm push-off! Even sneakers and flat shoes, which tend to make walking easier, can achieve ideal walking with the walking guide. Heel pumps also have gel grip that prevents slipping and provides stable walking. Even leather shoes, which can be uncomfortable because the feet are fixed, can be transformed into comfortable walking shoes with the walking guide and air support.
