I returned the first pair ordered since a 10 was too long (I wear 9 1/2, sometimes a 10) - and got a size 9, which is perfect--so order a size down if you wear a half-size. The sole is SO comfortable and cushioned; my only negative is that it can transfer heat at times and makes my feet a bit too warm (but I have specific health issues with heat/cold & very sensitive feet) ~ I had a good laugh over how to put them on, at first, since this style was new to me...had to refer to the directions for a couple of wears before I "got" how to slip my toes in, hold the band, then pull the sling back over my heel! This could be an issue for a more mobility-limited person. I will order these again if they wear well this season, and like the variety of colors & patterns to choose from. Very cute.
