I never said it wasn't possible. I said it was a reasonable consideration. They change the situation. For some people, the change is (or seems, which is more important) insignificant. For others, it becomes a problem because of their "pocket techniques". I'd be affected only a little by a change in clothing/shoes. Folks who kick more or use larger movements might be affected more. My point is that experimenting with different combinations is an effective way to find out.I have fought guys while wearing suits. short and raincoats. Slippery shoes sneakers and bare feet. In belt kit,with gloves on. Pretty much everything.
We had this elastic tie thing that was supposed to protect while in a fight. Can't remember it ever stopping a face punch.
I could have used knee pads to be honest. That was my big issue. Holding a guy down for 20 minutes untill the cops turned up. Hell on the knees.
The only issue with shoes coming of is if I got hold of one of theirs I would throw it on a roof.
