I love Keens but these just didn?t work for me so I returned them. This may have to do with having the feet of a Hobbit. My daughter likes them but finds them difficult to put them on by herself. I decided to check out Dr. Wasnt sure what size to get based off the reviews and didnt see a photo of the back of product where the size info is. I have this shoe in black and wanted to get navy to go with my jeans and dresses with navy in them. It feels perfect, very comfortable. I have a timer on it and when I get up I push ONE HOUR, get in the shower, and I have a amazing delightfully warm towel. Arrived on time and look like in good working condition. The next day it said 4 days out.
