Try different shoes too. The position of the heel in relation to the entire sole of your foot and your center of gravity can make a big difference. Even a 1/2 inch forward or backward feels different. All shoes are not made the same. I have several pairs of 4 inch heels and they all have their own "feel" to them. I have 2 pairs like these from MissHighHeel.com and I can walk in them all day long with no problems, they are as comfortable as my running shoes. And at $22 they are a bargain too!
