You know, after walking barefoot on hot blacktop or on pebbles or harsh gravel, the way you soles tingle for hours after, given how the sensitive nerves have been greatly stimulated..... mmmmmmmmmmmmmmmmmmmmm......
I never experienced that. What I get from "intense walking" is more like feeling my soles become rigid like hard rubber. BTW I finally managed to get an injury yesterday, note to self: when going through a heap of broken pine tree branches, don't rush. It was just a piece of skin the size of a cent though, no blood.
