Of course, this is just a bit of fun with a bit of truth. I personally train without shoes whenever I can and if I train in a gym where shoes are required, I wear Vibrams or Xero shoes. As long as the shoes are flat, not runners, and have a good-sized toebox, it’s all good.
I do wear wristbands when I do high volume and it’s super hot. The problem with wrist guards for beginners is explained here.
