Dark brown leather dress shoes with a lace-up design, perfect for business. ● These shoes feature the "GEOX SYSTEM," a patented technology from the Italian shoe brand GEOX, and are made with soles from REGAL CORR. (Regal Corporation). ● The GEOX SYSTEM is a unique technology developed by the Italian shoe brand GEOX for breathable and waterproof shoe soles. The image shows the sole of a product manufactured by the Japanese shoe brand Regal (REGAL) using this GEOX patent technology. ● About the GEOX SYSTEM Technical Overview: The technology is achieved by creating small holes in the rubber sole and attaching a special microporous membrane over them. This membrane prevents water from entering the shoe while allowing moisture (sweat) inside the shoe to escape as water vapor. Features: Also known as "breathing shoes," they create an ideal environment to keep feet at a comfortable temperature, with a major feature being their breathability and resistance to stuffiness. Used twice for a short period. I think they can still be used for a long time. *Please read the profile before purchasing m(_ _)m
