https://www.youtube.com/watch?v=Td6SyKyhuCk Eliminates complaints about recovery sandals such as being bulky and difficult to carry Recovery sandals are popular for their thick, soft soles and relaxed comfort. I wanted to use them when traveling or outdoors, but they were bulky and would make my luggage big, one of them would fall apart and go somewhere, and it was a hassle to prepare a bag… There was nothing that could be easily carried like portable slippers or flip-flops. In order to eliminate such dissatisfaction, we developed the recovery sandal “BUMPY” with the concept of “carrying comfort with ease.”

By stacking them on top of each other, they won’t shift easily and can be stored compactly. Furthermore, all BUMPY models have a function* that allows them to be bundled compactly using a size adjustment cord or an attached cord. (*Patent
pending)This allows you to feel comfortable wearing it and easily carry it anywhere.

The newly developed insole, which was arrived at through repeated research into materials and shapes, provides comfortable wear and a stable walking sensation. ■Original material “Repulsorb Plus” “Repulsorb Plus” is an EVA material developed by Hiroshima Kasei Co., Ltd. that has high impact absorption and elasticity, with rebound resilience approximately 130% compared to general EVA. It not only firmly absorbs shock but also has the property of moderate rebound, so when used in insoles it can reduce the burden on the feet and improve stability when walking. It has a soft texture and you will feel comfortable the moment you put it on.
Iron ball drop test comparison. BUMPY’s sandals hardly move, and the iron ball bounces higher, indicating that it has higher shock absorption and elasticity than regular sandals. ■“Toe hook” and “arch support” derived from the shape of the sole of the foot By creating a raised shape (toe hook) on the surface of the insole where the toes rest, it becomes easier for the fingers to grip the sandals, ensuring a secure fit to the foot when walking. It also has a three-dimensional design (arch support design) that fits the arch of the foot, supporting the arch of the foot and evenly distributing pressure on the foot.

Compared to the conventional product (right), BUMPY shows that pressure is distributed throughout the sole of the foot. Available in two types: travel & outdoor use and office & indoor use. BUMPY’s debut season will feature two types: PACKABLE, which is suitable for traveling and outdoors, and SABO, which can be used in the office and indoors. ■BUMPY PACKABLE
