Oh man, I don't know how this could be true. I work manual labor, in sneakers. I spend all summer recreational time in either flip flops or barefoot. So while I don't have huge callouses on my feet, I've got some. Not tender baby feet.

But still, one day it was like 70 or 80 out, I changed out fancy clothes into shorts, but forgot to pack my flip flops. I really wanted to walk down to an event that was going on, but I didn't want to wear black fancy shoes with my shorts. So I went barefoot on the sidewalk, about 3/4 of a mile.

I did like you said and walked in the grass a lot, but man the concrete was hotter than I expected. It didn't hurt at first, but each new step I took found freshly warmed concrete that just heated my foot more. Keeping moving definitely wasn't helping. Eventually it started to hurt, even with walking in as much grass as I could.

I got to where I was going, grass covered area, and didn't think too much of it.

When I went to leave? Oh man. My feet hurt. Looking at them closely, I had several blisters on both feet. I cooked em. I couldn't walk back, I had to call my friend to pick me up.

That was on regular concrete. I cannot imagine doing that on asphalt, I wouldn't make it a hundred feet.

Maybe I really do have tender baby feet 🤔
