This is an anecdotal example, I go running in 10lb forest fire boots and heavy blue jeans. I run with friends who all wear proper running attire. We all run the same pace. We do a few miles around a 6 minute pace. The thing is, any time I put on my running shoes and a pair of jorts, I absolutely smoke them. I start getting near 5 minutes flat on my mile. Sure it's hard, people would call it dumb. But wearing boots and jeans every day of my life and doing hard things while wearing them absolutely puts me far ahead of basically anybody that isn't a gifted athlete.
I don't even understand why people would practice things with the most efficient and easiest stuff. All you've done is create a factor that you can't improve on. All I have to do it switch shoes and pants and it's a new ball game. I like that.
