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

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.
