I purchased the J&M Melton's five months ago.  For the price they are one of the better dress shoes available.

I purchased in my typical size, 11D, and they fit as expected.  When compared to Allen Edmonds shoes like the Strand that I own the fit is very similar.  Also good quality of the leather and the craftsmanship.  The classic cap toe will never go out of style.  The biggest plus for these shoes is that they have a lot of the qualities you would expect in a much more expensive shoe for less than half of the price.

A few things to note:
The other reviewers are correct that these shoes will take some breaking in.  They are much stiffer than Allen Edmonds.  I don't wear these shoes all that often (probably once every other week) and there is still some work to do.

The leather is very shiny.  This could be a pro or con depending on what you are looking for.  For me they would look odd to wear with anything other than a suit.  Not great for jeans or chinos.  But on the positive side they are formal enough that you could rock them with a tux if needed and they would not appear out of place.

Overall, these are a good quality shoe for the price.  I would recommend to anyone that they spend their money on these rather than buying a cheaper throwaway shoe (and they don't want to drop over $300 on the AE Park Aves).
