Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.
