These are GEOX sandals. I've worn them once and stored them at home. GEOX shoes have a patent for their "breathable shoe" function and are so well-known that about 1 in 8 people in Italy wear them. Also, the innovative sole uses a uniquely developed material called "membrane." This material has microscopic pores that are smaller than water droplets but larger than water vapor. By sandwiching this material between the holes in the sole, it prevents water from entering from the outside while reducing stuffiness inside the shoes, a feature for which they hold a patent. This makes them comfortable to wear even in the height of summer. The size is LL. I remember that they cost around 25,000 yen when I bought them. Several years have passed, and they have been stored at home. Please understand this. If you have any questions, please leave a comment. Thank you!
