Just Reduced! NIS Bio Comfort Air On Feet Women’s Slippers. These are Marked Size 39 and they Slip On. I normally wear a U.S. size 7.5 and I feel they fit me with a little extra room but not a lot. I cleaned my foot before trying on for the photo. Everyone has a different shaped foot so they may fit you differently. These have a real shoe bottom outsole allowing them to be worn inside or outside the home. Air on feet insole provides cushion and comfort. They are made in Italy and have a cute embroidered edelweiss design. I have a hard time with colors so my guess is that these are mostly black with other accent colors but what I think is black could be another dark color. These are preowned and used but they were not worn very much. They show some all over wear and have some minor imperfections but have lots of life left in them. Measurements are a rough approximate. Colors may be off because of lighting.
