I am selling this item because I have a new stingray guard. In recent years, the population of stingrays seems to be increasing nationwide, so if you are wading in rivers, estuaries, or the sea, why not consider purchasing this? The sense of security when wading is definitely different depending on whether or not you are wearing a stingray guard. It is a Velcro type and easy to secure. The size is LL (approx. 27cm). My foot size is 27cm, but it seems a little larger than the listed size, as I can wear it even with ankle socks and thick socks. As you can see in the photos, there is some wear and tear, but the performance is not affected. Manufacturer's suggested retail price (including tax): 41,800 yen #StingrayGuard #RayGuard #RayBarrier
