GREAT shoes that last forever! You can wear them top or bottom and they are perfect for people who don't wear socks. I have three pairs of Minnetonka moccasins, but this is my only double bottom version. The only difference is that they are a bit heavier and the rubber outsole is a bit thicker. Given the double full leather construction, they were surprisingly flexible and pliable right out of the box. I wear minimal shoes (the thinnest sole, virtually no arch, no padding, no socks) and this is thicker than ever (probably 0.3-0.4 inches at the thickest point). They will stretch a bit over time, but they can be tightened by getting them wet and allowing them to air dry.
