I have purchased Keen way back when and fell in love with them. They are comfortable, form to your feet, and washable. I was unable to purchase the Retro pair at our shoe store. I wear size 12 in womens or 10 in mens. They didn't have size 12, which it does not come in, and they didn't have the Retro in mens. So I looked online and found them. I was ever so happy. So I ordered the Retro, and I love them. The Retro colors are bright and so cool.
