TOUGH SUMI XL

"unda" is a combination of geta sandals and sneakers

The midsole is made of PU material and an air sole, adjusting the hardness to the optimum softness. The air sole further reduces shock, making it feel like walking on clouds. Furthermore, since geta sandals have no left or right, by regularly switching between left and right, the sole's lifespan can be extended without wearing down diagonally due to walking style or foot habits, and this is why the symmetrical design was adopted.
