Birkenstock Unisex-Adult Zermatt Shearling Wool Adjustable Mules Slippers - Cozy Indoor/Outdoor House Shoes for Men & Women - Perfect for Home, Office & Winter Comfort

I’m a 6 1/2 with narrow feet, and I have spent and wasted money on different slippers that would only stretch and become uncomfortable and kind of unsafe. These Birkenstocks are fantastic. Finally, I said to myself finally I should’ve started here first.A month later, wearing socks or without socks, they keep their shape and they’re still comfortable. Best purchase.
