These leather upper, man-made, Sherpa-like interior slippers will definitely keep you warm and toasty in the cooler months. The wool-like (but it’s man-made material) interior is throughout the inside of the slipper. They say size 7 but are about 25 -25 1/2 cm long and a little over 9 cm wide ( at wider area, not toe). These could definitely be unisex. My guess is the size 7 is men’s. I’d say they are a women’s size 8 after trying one on (I’m a size 8 1/2 and are snug). They have only been worn once or twice and are in very good condition. They are from a smoke-free home.
