The Quoddy True Penny Loafer fits true to size. For reference, I wear a 7D in Alden's Barrie last. After breaking in these loafers, I added a tongue pad to tighten up the vamp (size large from Amazon). I don't think I could have sized down to a 6.5D since my toes would touch the end of the loafer and a wider shoe would definitely mean walking out of the loafer. The width of this shoe is such that it squeezes my feet so that they don't slip out of the shoe. The leather sole and vibram heel add additional comfort. The glove leather lining is extremely comfortable with dress socks and there is an option to go sockless in the summer time. I would recommend a tongue pad for anyone out there with slightly loose fitting loafers when sizing down or getting a wide size is not possible. You won't even notice it's there after a while. After several months of wear, the leather still smells divine. I'm looking forward to wearing these for a long time.
