Our BROGUE style is based on our archival EMPEROR™ golf shoe, introduced in 1970. The upper is made from leather. Every detail has been meticulously engineered for both form and function. The inner sole is made from various materials in varying firmness, including αGEL Foam, for excellent cushioning, arch support and shock absorbency. The outer sole is made from rubber sponge, combining both durability and cushioning. Its form is based on training shoes from our own archives, with a shark sole treads and circles at impact zones. *αGEL Foam is a trademark of Taica Corporation, registered in Japan and/or other countries.
