The Xlite soles seem to only be used on AE's crappy made-in-Dominican Republic shoes. Plus, aren't those soles just glued on? The Nomad if it was made in the US with shell would probably not use the XL.I also think a Nomad in shell would be nice, but really what I want is the XLite sole to be offered with a shell shoe. Now, what would you say to a Williamsburg in shell?
Unfortunately, the Cornwallis is no longer current. I think the Lake Forest is also being discontinued.
The Nomad and Williamsburg are pretty similar shoes, so I'd say they both could pull it off. Chukkas look nice in shell.
