I own three pair of Keen shoes, all the same size, so I ordered this Targhee II Hiking shoe (it is not a boot!) in the same size as my other Keen shoes. The shoes were slightly too small, so sent them back. Here's the catch - I had to pay $13.79 to return the shoes - therefore, I was not about to order the next size up, have it not fit and pay to return them as well. They shipped for free, and I thought returns were covered, too. Pays to read very carefully when ordering from Amazon.
I bought the same shoe through another vendor which included free returns.
This vendor did charge less money for these shoes, but it is only a deal if you don't have to return the shoes. Nevertheless, this vendor promptly sent my order and refunded the money within a day of receiving the return.
