I just can't get enough of barefooting hot sidewalks. Not burning-flesh hot, but toasty-warm, reminding me that my bare soles are traversing something I'd never feel with shoes. Same pleasure derives from walks in the rain, especially in mud. I go commando, so all of me gets aroused!
I, too, like the feel of warm concrete even black top on the bottom of my feet. Strangely, perhaps I also enjoy the feel of frost on my soles.
I also love warm concrete and blacktop under my bare feet but a also love the feel of cold concrete and blacktop and cold grass and snow under my bare feet
