How to Stretch Leather Shoes

I bought a pair of deadstock wedges on eBay only to find that they're a little too snug. I've broken in shoes that fit like this before, but it's a long and painful process that is usually paired with purse stuffed with flip-flops. I'm looking for a shortcut. One suggestion came from a Bloomingdale's salesperson:

Mix rubbing alcohol and water on a cotton ball
Saturate the leather that I want to stretch
Stick feet in shoes
Repeat once dry

Anybody have other suggestions?
