I had high hopes for these.  I read that a lot of people found the nodules on the soles uncomfortable, but I'm not super sensitive to discomfort so I thought I'd be okay with these.  I didn't find them uncomfortable when I first tried them on.  I noticed that they weren't exactly comfortable, but I didn't find them painful.  Until I wore them outside while I gardened for a couple of hours!  I could barely walk by the end of my first wear.  Since I wore them outside, I couldn't return them.  I'm stuck.  Also- note to yourself- I left them by the pool for two days and the pink on the sole has faded to a really ugly peachy color.  What a boondoggle.
