I'm planning on getting mine resoled, and like everyone else, I would rather wear them down myself than have the cobbler sand them. Taking that first step and scuffing your sole is a little traumatic, but you keep going and it really is nice that the red doesnt stay, its too slick.
I'm going to have to do it soon, already the sole is really worn on my brown and black VPs. I wear them so often that there is no red left on the ball of the foot area!
