OUTDOOR PRODUCTS Size: 20.0cm Used a few times. Stored after washing. Some minor dirt and signs of use, but no noticeable damage. (From the official website ↓) 4cm x 6-hour waterproof specification makes it difficult for water to enter the shoes, allowing for comfortable walking even on rainy days. The calf area is down-filled, providing good cushioning and warmth. The insole is removable, so it can be washed and kept clean. Thank you.
