It’s what “geezers” diabetics, leftists and northeasterners (but I repeat myself) on vacation to Florida wear.
It is what it is.
I wear olukai flippies (the BEST,most comfortable)
...but then again being cool comes naturally for me =o)
Tatami (Zori) flip flops were always my favorite and most comfortable summer footwear; they squish down nicely to the shape of your foot, and remain nice and ‘springy’.
You used to be able to buy them for a song in the drugstores here; now I have to hunt them down online and pay a lot more. (The last time I bought them, I think I had to order them from a Karate/Marital Arts outfitter.):
