Generally, clothing cut should match your build. I think shoes go along the same lines. A big dude wearing dainty shoes will look a bit off.Not so much on the price but rather on the looks. I was quite pleased to see a shoe design that I liked at that price, but after reading some reviews, I found out it has quality issues that cannot be ignored.
I have AEs in Black and Brown (since they come in Wide and Extra Wide), but they are on the clunky side. If I can find a sleek looking shoe at no more than $400, then good.
If you were 120lbs, I'd absolutely agree with seeking out what you are. At twice that? "Clunky" will look better and more proportional on you, quite frankly.
