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.
