Those look like the current New Orleans, I had picked up a pair in black and walnut earlier and like them so much I ordered the Boca Raton when they put on the Fathers day sale. It's amazing how cool they feel, considering that they are fully leather lined. I guess one thin layer of solid lining leather under the woven area is cooler than two solid layers, but I can definitely feel the difference, which is noticeable when sitting in the living room with a ceiling fan going. As much as my feet sweat these shoes are going to get a good workout this summer.
I'm in the same boat, I loved the Lauderdales so much, I picked up a pair of discontinued Hampsteads for a bit more of the wingtip vs. captoe look. Both are just outrageously comfortable and, as you said, much cooler than a comparable non-woven shoe.
