FIVE pairs might be somewhat redundant, etc, but having, say three, pairs of shoes might help. Once you start climbing hard stuff, shoes might make a difference. Then again, I'm talking out of my ass since I'm the guy who used to climb everything in Aces. They died, and Thinkmountain.com hasn't sent me new ones yet. I'd say for the vast majority of climbing, one or two pairs of shoes will cover it.
