I was really hoping to find the Keen to be the perfect mix of slipper and shoe to wear in the house, but also use if I needed to pop out for the mail. What arrived was a nicely manufactured item that lacked important features. This review is also a review of the customer service aspect of returns which I felt were not comparable to other online merchants who now offer free shipping and returns. In this aspect Amazon is behind the times. These are shoes, and shoes are difficult to get right in terms of sizing, etc., but if you have a sizing issue, you will pay $5 to ship it back. Not cool.

1.) There was not enough flex in the fabric. Since this is a slip on this is important. I looked at some of my other slip ons and these had two flexible notches in the front of the opening rather than a fairly weak one on the side. If they rethought this design to allow for more flex it might be a better shoe.

2.) These seem to run about a half size small. So, this might be the reason why I needed more room.

3.) I was not happy paying nearly $5 to send it back and that this was deducted from my refund. I think the other shoe outlets are now offering free shipping and return. I thought it was lame of Amazon to take this out. I will think twice about ordering shoes from Amazon but might look to the other big online shoe sellers who won't hit me $5 for a sizing issue that was no fault of mine. The dumb note they included when I selected return was annoying: Since it was not our fault, you have to pay to ship it back. Nice. Really nice.
