Kendo Heel Supporter Brand new, unused. This is a 10mm thick, Japanese-made heel supporter with low-rebound shock-absorbing sponge. It contains rubber sponge to cushion the impact on the heel when stepping in Kendo, making it effective for those who can't step in due to heel pain, and for preventing heel pain. The sponge inside is made of low-rebound shock-absorbing material that absorbs the impact of stepping in and reduces the burden on the heel. It is firm and resistant to crushing, ensuring long-lasting use. Available sizes: M, L, and LL. Size M: For shoe sizes 24cm and under Size L: For shoe sizes 24-26cm Size LL: For shoe sizes 26cm and over They fit a bit snugly, so if you have a high instep or wide feet, please choose the next size up. We have plenty of stock in each size, so you can buy immediately. Please specify your size after purchase. Due to the nature of the sponge, it will harden in the winter when the temperature is low, but it will gradually soften as your body heat warms it up when worn. If you are concerned about the hardness before wearing, warming it up will soften the sponge inside. Shipping will be via standard mail, so it will take 3-5 days for delivery.
