I don't really care for the shorts and boots look on females...especially not those boots that look like snow boots, worn with shorts and a halter top, and it's 90+ outside.
On men, no way!
I don't ever wear shorts in public...not with sandals or tennis shoes...not at all, period. I wear them around the house all the time, but if I'm going anywhere that I have to get out of the car, I put on pants. Why? Well, I have to wear compression hose, since I've had issues with blood clots in my lower legs; these hose are black, and they look like knee high stockings. Women's knee high stockings...not men's over the calf socks. No way am I going to be seen in public with those showing!
My wife thinks I am being silly...but round these parts, a man wearing shorts with knee high stockings could get beaten up! No matter what footwear he was wearing...but boots would make it even more likely.
