I like to run around barefoot a lot (which is interesting in the city sometimes... ), and my footfall is entirely different with and without shoes. No shoes, I walk toe-heel, or more specifically ball of foot-heel; with shoes I feel like I'm clunking around going heel-toe. It feels rather like my feet are blind. People who are always strapped up in hard shoes probably find the phrase "my feet feel blind" weird, but I can't think of any other way to say it. It's like when I first learned to drive a car, I did it barefoot, and could feel the engine through the pedals. Then someone told me it's illegal to drive barefoot (which apparently isn't true? But I didn't know that in the 90s), so I had to practically re-learn because I couldn't feel what I was doing with my feet and how much the engine was revving. This was most notable driving stick - barefoot, I could feel when to change gears, but with shoes on, I was like, "WTF am I doing, AAAAAHHHHH!" LOL
