It does come in a B width. The Overview says it is made with Horween Chromexcel. This is for the upper. The "imported leather" on the Details section refers to other parts of the shoe. I'm not sure what you are referring to about the "black welted leather edges." The AE is a goodyear welt, and the Rancourt is a Blake. Here is an article showing the differences:
John Lofgren Monkey Boots Shinki Horsebuttt - $1,136 The classic monkey boot silhouette in an incredibly rich Shinki russet horse leather. 
Grant Stone Diesel Boot Dark Olive Chromexcel - $395 Goodyear welted, Horween Chromexcel, classic good looks. 
Schott 568 Vandals Jacket - $1,250 The classic Perfecto motorcycle jacket, in a very special limited-edition Schott double rider style. The black welted edges I referred to are along the tongue opening along both sides, the rough tongue surface are IMO unappealing also. While I agree the B appears to be available initially, when clicking on sizing, the B isn't highlighted in gray, thus I assumed it wasn't available. While I initially assumed the Horween leather was USA based, I was referring to "imported leather" mentioned in the Details section. I found out the "Byron" is available with a similar sole labeled a "Dalton", USA sourced. Thanks for the construction piece, It certainly makes a difference as I highly doubt there's a shoe repair in my little town which has a Blake machine for replacements.
