Amphibious shoes, currently selling for ¥26,000

These are water shoes from Astral, a river kayaking equipment brand. The current models sell for around 26,000 yen, but this model has a more town-use-friendly design. As shown in the third photo, water drains from a slit between the heel's upper and the sole. Additionally, as seen in the eleventh photo, there are six drainage holes in the sole from the toe to the base of the toes. The insole is made of a material that doesn't absorb water and can be worn barefoot. They are perfect for situations like barbecuing by the river and wading into the shallows to cool beers in the river water. Light water sports are also possible. The size is listed as 27cm, but they fit me perfectly, and I usually wear a 26.5cm. They were used only once in a mountain stream. There is some discoloration on the insole, but it is adhesive from the manufacturing process, not dirt.
