I think these would work for someone whose feet are not at just the wrong in-between size that mine apparently are. I typically wear a 6 or 6.5, so I first ordered the size 5-6, thinking that a somewhat snug slipper would be okay given the style of shoe. Those were way too small (they pinched badly) so I ordered the next size up...those ended up being a tiny bit big. I had hoped to use these for the points on my wedding day when I didn't want to wear my heels, but since neither size was truly a good fit, I opted for other alternative shoes. I really liked the concept, how flat they fold up, and the included storage pouch was nice.
