Does anyone wear them to run? 
what about in the club ? 
Why would you do that? You can run barefoot on a treadmill, but I recommend that if you run on a treadmill you get yourself some good running shoes.
I don't, I saw someone at the gym wearing them and thought it was a bit odd and wondered if anyone else did on here.
Uh no
Seems like a really fast way to destroy some expensive shoes to me.
boxing shoes are for fights or sparring days. Running and training in them is a good way to get shin splints and fuck up your boxing shoes.
Only if u need everyone in the gym to know u box lol.
