Beyond my expectations
Size: 10 Wide, Color: Mocha Grainy Leather
Really nice shoes. Wide enough and comfortable I’m keeping these.

Good Fit Out of the Box
Size: 9, Color: Black
The shoes came with the correct size and is a good fit. They were originally pretty stiff, but are much better now after breaking them in. They look good. but as other's have said, they are made of synthetic leather and in my opinion have kind of a plastic look to them. The quality is good with ridged rubbber soles. I thought they were kind of expensive, but then again I haven't purchased these type of shoes in a while. A family member told me that if they were real leather, they would have been a lot more expensive. For what the shoes are I would recommend the purchase.

Sleek and classy loafer
Size: 10.5, Color: Black
Was skeptical on this purchase but I have to say, well worth it. Not super expensive but very comfortable. Wears well for summer dress attire for taking your lady out for a dinner or show. Casual yet classy.
Not a bad buy.

I wanted to love these
Size: 9, Color: Black Leather
These are very good looking in person, especially the buckles and the pop of red on black.
Alas, I have another pair of Marc Joseph shoes to compare comfort and fit, and this pair simply hurts my feet.
