Experience the perfect blend of style and comfort with these Birkenstock Tokio mules. Featuring a classic closed-toe design, these shoes come in a versatile white and brown color combination. The adjustable strap with a metal buckle ensures a secure fit, while the contoured footbed provides all-day comfort. Size 40, I wear a size 9 and these are big on me, even with socks. If you are a size 9.5 or 10, I think these would be great. I got them second hand so they are used and worn!!! But there is still a lot of life left in them.
