These are vintage Tatami by Birkenstock slide sandals. Tatami was established as a high-end, premium sub-brand of Birkenstock, known for incorporating more elaborate upper designs while retaining Birkenstock’s iconic orthopedic support. The filled-in footprint icon indicates a regular/wide width fit. They feature a thick, deep-brown leather upper band paired with an anatomically contoured deep footbed that provides superior arch support. Unlike standard cork-exposed slides, this premium Tatami iteration wraps the footbed lining in a soft, dark suede or leather finish for a dressier look.
