thin-soled cycle touring shoes
The Quoc Pham shoes are nice: they do recessed-cleat "touring" ones, but also plain leather shoes with thin, fairly rigid soles, suitable for flat pedals or toe clips &amp; straps.  They seem to have a US distributor, Mission Workshop.

I've seen the Dromarti ones advertised as well, but don't know about their distribution.

These Exustar ones are apparently useable if you just leave the cleat cover in place.

Finally, Vittoria have the 1976, and seem to have a few US distributors, so they might be worth a look.
