I tried out a pair of Dooey's house loafers, and sadly, the front portion is too tight side-to-side for my problematic feet.
To initiate a return, the procedure is to send them an email. When I did, I received a reply from Jordan, their founder, within about two minutes.
In addition to providing a return label, Jordan said that they will be adding new sizing options over time. When they do, I will definitely give them another go!
