Thank you for viewing. This is a TLS 5mm 25cm warm wetsuit boot. This boot is brushed inside for warmth, and the big toe is separated from the other toes, making it easier to grip the board, which makes it a very popular boot. The price is 6600 yen, as it is a display item, whereas the regular price is 10230 yen. We also have 3mm and 5mm boots in various sizes: 20cm, 22cm, 23cm, 24cm, 25cm, 26cm, 27cm, and 28cm. Please feel free to ask any questions. Shipping will be via Kuroneko Yamato cash on delivery. This product is also sold next to Sushiro in Kamakura, so we apologize if it sells out.
