Shock-absorbing insoles that prevent tired feet. Excellent cushioning. These insoles feature a 5-layer 3D structure using PORON, a shock-absorbing material, and provide arch support, making them less tiring. They are neither too soft nor too hard, with a moderate elasticity. The toe area has a wavy texture to prevent your foot from slipping inside. Also, the surface is a pale greige color, and the logo is understated, so they look elegant even when you take your shoes off. However, they are quite thick, so they are suitable for shoes that are 0.5-1cm larger. Due to the thickness, the heel may also become shallower, potentially making the shoes easier to slip off. It is recommended to put them in larger shoes or shoes where you feel the heel or ankle area is deep. They will also make uncomfortable boots and rain boots more comfortable to wear. This is a men's L size, which I cut to the 25.5cm guideline and it fit perfectly in a 25cm shoe that runs large. Note: It is recommended to cut them 0.5cm larger than your actual shoe size and try them out. I used them only once, but I no longer need them because I got rid of the shoes themselves.
