I bought 2 pair last year, and I have been so pleased with the all day comfort of these booties that I bought 2 more pair this year! So now I have 4 colors!! I just hope they will bring them back next year in case I need to replace a pair. I have flat feet and back and neck issues so I get really excited to find something stylish AND comfortable... hence the 4 pair. Yeah, they're that good!! I usually wear a medium and I have one pair that is medium width, but with these, I do prefer a little extra room and have ordered the wide. However, medium is fine too.
