These are so nice and stretchy! Stretchy but not so stretchy that they fall off my feet.  The memory foam is really nice.  Ive had bunion surgery on both sides of both of my feet.  My feet are still wide and I have high arches so finding shoes is tricky.  Finding shoes that have some style is nearly impossible.  These hit the mark all the way around, stretchy around my problem areas with enough room to allow for my high arch.  Not too high so I can walk.  And finally something a little girly.  Im thrilled with these!
