Quality boot, Works with blue jeans or nice slacks. Very comfortable and well made.
SIZE Does mater. I ware  9-1/2-D in every thing even a pair of this brand in 9-1/2 D.

But if you read the reviews, 2 sizes smaller are perfect. I ordered a pair of this Florsheim Joaquin Boots per other reviews in 8-1/2-D and they are perfect fit.

I aways been happy with Florsheim.
