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.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

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
