I'm barefoot more and more these days but mostly inside.
Outside in our damp UK climate to walk on the path or garden you get wet, dirty or muddy feet. Whilst that's no problem to me personally...a nice squelch around the garden is nice and earthing as per Bob's video...the problem is when you get inside the house again and have to go through the rigmarole of cleaning the mud or whatever off before you go into the house. I find this tedious and time consuming even if only a minute or two as it delays you whilst doing some other task or other so if the ground is not dry, I slip on a pair of mock crocs (like croc shoes but only costing a few pounds from a cheapo rip off store!) or clogs and just shrug them off at the door when I come back in.
I wish I was bold enough to be really bohemian and go barefoot everywhere, like Bob, but again, there are 2 good reasons I don't: First, I'm afraid of injury. The streets where I live are full of foot ripping hazards such as broken kerbstones and so on pls the tarmac pavements are quite hard on the feet. Second, I just can't be bothered to challenge all the prudes and rigid conventionalists out there ("ooh aren't your feet cold?" Visitors say this to me even when visiting our house. NO! they obviously are not, dork visitor, otherwise I would be wearing shoes!!) and again as Bob has mentioned in the past people don't like bare feet in their shops and so on - although with customary textile hypocrisy, everyone tolerates the equally or more dirty soles of shoes!
So in the warmer weather i.e. from now on I stick to some more minimal footwear as much as I can - usually Fit Flop thong sandals or other thong sandals.
I particularly like wearing thong sandals as the sun is setting and as it begins to get dark, I sing this song: "Just a thong at twilight, when the lights are lowwwwww!!!"
