This is my first pair of Aerosoles, and after wearing these, I've ordered 5 other pair (different styles).  They're cute, unbelievably comfortable and offer plenty of support for problematic knees, hips, and lower back, and (no offense to anyone), they don't look like orthopedic shoes.  No blisters even though I wore them all day right out of the box.  Will likely order in a different color.  You won't be sorry if you order these!
