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

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.

Warm, Comfortable, and Great Value!!

Material Type: Recycled Polyester, Color: Black Red Buffalo Check, Size: Medium

This fleece is cozy and does a good job keeping warm in cold weather. The material is soft, the fit is comfortable, and it layers well over a shirt. Not heavy-duty outerwear, but perfect for everyday wear and great quality for the price.
