I've told this story on here many times, so one more time isn't gonna hurt.  Went through the same thing years ago.  My feet and back hurt so bad that I could barely function throughout the day.

One day, I went to get my haircut, they were backed up, next door was a Red Wing shoe store, so I went in to browse.

Started talking to the guy, He says, and I quote. "Your back and feet hurt because you're wearing shitty shoes".

"These are pretty expensive shoes"  I said.

"Doesn't mean they're not shitty".  He chuckled.

He told me if I bought some Red Wings boots from him, my lower back and feet would stop hurting within 2 weeks. If they didn't, I could bring the boots back and he'd refund my money.

Next thing you know, he's putting my feet on a computer scale, really taking time with proper sizing, etc.  (like they did when we were kids).

Less than a week later, my foot and back problems were 100% gone. 

Now, I've got a "boot guy".
