Gyosan (sandals for fishing industry workers) Non-slip and durable, they can be widely used from the sea and pool to everyday wear in the city. I bought them in Hachijojima, but I'm selling them because I don't have a chance to use them. • Size: M They fit perfectly on my heel at 23cm, so they might be just right for those who wear 22.5cm. • Color: Brown • Made in Japan • Non-slip even when wet, perfect for the sea and pool • Easy to walk in, also great for everyday summer wear
