Now I never wear shorts (and I go to hotter places than you) but simple white sneakers like gnatty suggested should work fine. Try to be less golf/boating and more casual summer, these aren't the same. You don't need to pay a lot for sneakers and thin man should be able to find some canvas vans, plimsols or something like that that work. In the absolute I think there is always someone, somewhere that can pull off a piece of clothing but you're better off banning polos, loafers, boat shoes, maybe even shorts because chance are you aren't that person (this applies to everyone).
I see sneakers as shoes to be worn when working out. I just don't feel comfortable in them and never feel they work with anything as well as a loafer. Again, as discussed with Hendrix, this is just a difference in ideologies. Agree to disagree about the utility and appropriateness of sneakers vs. loafers.
As someone who has lived the majority of my life in the Southeastern United States, I'm not sure where you are that is hotter (or, perhaps more appropriately, more humid), but I'll assume there are hell holes out there I am unfamiliar with. Regardless, I run hot naturally and am forced to wear shorts. I prefer pants, but I can only stand so much heat and sweat does no one any favors.
I agree that "casual" is not the same thing as "golf/boating" attire. However, I am simply most comfortable in "golf/boating" attire (for the record, I would not categorize my style with these words at all, but I think you're on the right page, at least with your limited knowledge of such an aesthetic). So then, you're asking (or better yet demanding) that I change my style to something I am uncomfortable with just because you are uncomfortable with my natural style. You do see the ridiculousness of this, right?
At the end of the day, just because you don't think something looks good doesn't mean it's wrong. Nor does it qualify you to make sweeping generalizations about what is and is not proper. This type of thinking is reminiscent of the absurd "MC dresses like adults" crap that surfaced a few months ago in MC WAYW. There is no right and wrong. It's what you're comfortable with and what you most readily identify with.
