I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

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.

One of the best shoes

Outstanding. Fashionable, most comfortable and good construction. No sines of use after quite some time. Highly recommended.

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.
