Unusual to NOT be ticklish on soles of your feet?

Factual Questions
1

How common is it for a person to find a light scratching sensation (for ex. someone else gently running their fingernails over your skin) on the bottom of their feet to be pleasant, and not ticklish?

Me, you’d have to scrape me off the ceiling - but My IT Guy absolutely loves it, which I’ve never encountered in another human being.

Anyone here not ticklish on their soles?

(Mods, I dunno if that makes this better suited for IMHO or not but I was hoping for a somewhat factual answer if one exists.)

I’m not, but that’s due to frostbite - I have significant areas of numbness on my feet from that. I can’t say have my soles tickled feels any particular way because I largely can’t feel it.

I’m not ticklish on the soles of my feet.

In fact, there’s that “test” where you firmly run a finger up someone’s sole and look for the toe-curling reaction. It’s supposed to be involuntary. I don’t do it. My wife, Pepper Mill, finds this freaky, and insists it’s proof that I’m dead.
