"I'm one of those people who just CANNOT find a comfortable shoe. I have hereditary bunions, and my feet ache in heels, in flats, in open toed shoes, in closed shoes... So when I saw good reviews for this pair, I went to my local store to try it. And since it seemed quite comfortable, I bought 2 pairs. And I'm so glad I did! It really are the most comfortable shoes ever!! The heel size is perfect and I can wear it all day without my feet aching. I travel and have worn it from morning through a work day and maneuvered through airports in these and have felt not a stitch of pain. I usually am between a 7 and 7.5, and ordered 7.5 in these. It is perfect for me even in M width (since usually I have wider feet). Love, love these! Am ordering in all colors!"
