Hello! ☺ Thank you for viewing. Size: 26cm~27cm Brand new, unused 【Shock Absorption Material】This insole has the strongest shock absorption and high cushioning among our products. It is designed to firmly protect the heel and arch, which are particularly susceptible to impact. By using high-absorption gel and low-rebound TPU material, it enhances absorption capacity and reduces the burden on the feet. 【Addresses Foot Problems/Strain】It is effective for flat feet, plantar fasciitis (tendonitis), and bunions, as well as for knee strain. It is an insole that protects your feet from all angles, including shock absorption, arch support, and overpronation prevention (heel support). *Note: This product does not guarantee the reduction of foot strain. 【Deodorizing Performance】As a measure against stuffiness inside the shoes, the surface material uses highly breathable mesh material. It may not fit in tight shoes, but it can be used in various shoes such as sneakers, business shoes, safety shoes, and golf shoes. 【Effective for Fatigue Prevention, Even for Standing Work】In addition to the shock absorption design, the TPU material (heel cup role) suppresses the wobbling of the heel, which causes fatigue. Pressure distribution and heel stabilization alleviate the burden on the muscles. No stains, tears, or odors...
