Here in hot funky Texas a majority of us (retireees,tourists,aliens,and boomers) wear SANDALS! Yes sandals- the kind with the luggage-type fasteners that click in and out for fast removal are the choice (Birkenstock-type). Caution-get them at least one size LARGER, this will protect the toes much better. Our feet are healthier and uglier for it. We wear sandals with or without socks. Socks are worn after5 usually. I buy from Thom McCann or anywhere cheaper ones are sold. The downside perhaps is that feet will have tan lines!
I wear Nunn-Bush wingtips otherwise (oxblood color mostly). Tip: always stow boots and shoes on their sides for better ventilation and drying. If wet, stuff newspaper in them to absorb the moisture. As is posted, Rotate daily wearings. Footwear lasts much longer. Never take good feet for granted. Ask any infantryman about that!
