This is an amazing looking pair of men's Juno New York hide and leather loafers. They are made so well and are even nicer in person. The top is a hide but not sure if it's pony or cowhide but either one is fantastic on these loafers. The bottom is rubber with plenty of life to them as you can see in the pictures. The leather is top quality which I've tried to capture in my pictures. The stitching is also great on these shoes.The inside reads 45 which is equivalent to a 12 US but I noted the size as 11.5 - 12. These will also work if you were an 11.5. I find that with loafers such as this you have the freedom to go down half a size if you really love a particular loafer. I included the measurements in the photos just in case that helps...
