I didn't have any for years, I always took my shoes off to go to the bathroom. Then I found my ex-wife's covers and I tried them a couple times, but I always stuck anyway, after using the covers.
I got new shoes last year that came with fancy covers, so I tried them, and I stuck after using them, so I just went back to going into the bathroom in my socks.
Probably my imagination I was sticking, but, that was my perception.
