Dr. Scholl's Exercise Sandals

I had a red pair of these wooden Dr. Scholl's sandals. Around 1983/84, everyone was wearing these things. I was in 3rd grade and my friends and I used to run around on the playground in them with no problem, but looking at them as an adult, I wonder how they could have possibly been comfortable? I would like to get a pair just to see, but at $88 in 2018, I think I'll pass and just remember the nostalgia!
