Every guy needs at least one good pair of dress shoes. When it's time to invest in your next pair, keep in mind these shoe shopping tips from men's fashion blog Kinowear. They will help you differentiate the quality shoes from the cheap ones.
The soles of the shoes can be a big quality indicator. They should have stitched (rather than glued) soles, be made out of leather, and at least a 6mm thick. Kinowear also suggests looking at the welt -- the seam where the sole meets the upper part of the shoe:
It should be visible, but it shouldn't extend so far past the edge of the shoe that it creates a ledge.
Make sure that any oxford-style shoes don't lace so tightly that the shoe edges meet. If they do, get a narrower fit or size.
