Unless you value looking expensive more than you value your joints and tendons, in which case, Prada all the way.
If we replace expensive with good. Yes, I do. It is not as if I have any problems with my joints, and, by the way, I have been to the gym in formal shoes a few times now, and had no problems.
I do not think you realise how minimal my use of the gym is.
Besides this is a pointless issue.
