In reply to Conor1:
"Most approach shoes are pretty shoddy to climb in, so you'll probably be best off buying a good pair of running shoes and getting them resoled with dotted Stealth C4 sole"
Surely approach shoes that have been designed for climbing would be ten times better then a pair of running shoes, unless you wear minimalist running shoes.
The quote that you have used does not really answer the OP, as it was spoke by a man regarding speeding up multipitch routes.
