How to break in new heels: try walking around in them while wearing slightly damp socks - will soften them and stretch them out. Use a small piece of sandpaper (medium coarse) to scuff up the bottom of the shoe - will help prevent slipperiness. Place moleskin on painful areas of foot & soak feet - it will expand and stretch out that area in the shoe. Put a large potato in the shoe overnight to stretch it out. Use hairdryer to soften it then bend shoe about to loosen it up.
