They weren't exactly inexpensive, around $15, but since September 19, when I originally identified them, and now, they are no longer for sale at any price on Amazon.com. And no wonder. Only one star out of five.
So with neither of the first two candidates viable, I am pleased that my readership has already chipped in a couple of suggestions.
Lona suggested unshoes, which I need to look into. She says they look like you are wearing shoes, but you are really barefoot, confounding those "no shoes no service" people. But so far when I looked for unshoes on the internet, I found these
which don't fit the descriptions, so I need to do some more research. Tara suggested "Loud Sneakers" which was pretty cute, 'cept I originally thought she said "Loud speakers". Contemplating wearing those, I thought of this trivia question: Whose sandals were "herring boxes without topses"?
So the footwear category is wide open. So keep those suggestions coming in, and also think ahead to the next category, which will be HEADWARE.
