I think that's the real point. Don't worry about the profile if you're talking about an Indy boot. A big rubber sole looks fine.
at the same time it's not going to look huge. I happen to be wearing my Ultimate Indy's with Commando. here you go. (these get very little love, shoe trees sometimes, sometimes polishing, wear in any weather etc)
LOVE THOSE. Guess I'm pulling the trigger.
