This would be a nice, casual alternative to a classic Desert Boot. This one is by Cucinelli. It has a lightweight rubber sole.
Speaking of lightweight rubber soles, have any of you looked at the new range of suede bucks from Walk-over. These are made in the USA, suede derbys with a calf lining, just like the original suede bucks from the 1940's - 60's. I just bought a pair.
