Surf Grip surfing boots, retail price 10,980 yen. Size is XXL (28cm). I purchased these at Murasaki Sports last year and used them about 3 times, but they were too big for me, so I'm selling them. I usually wear 26.5-27cm sneakers, but these were too big, so I think they would fit someone who wears around 28cm sneakers. Please check the size on the manufacturer's website, etc. They are very warm and soft, making them easy to put on and take off, and I recommend them. Surf boots
