Can someone teach me how to walk properly in pumps so that I won't feel so terribly sore after wearing it for a day?

I bought my first pair of pumps which has heels of height 3 and a half inches yesterday. It was so cute, so hard to resist and the main point was it has the size of my feet! But after wearing it today, I realised it was a tad too big for me. Can you believe it? Miss Big Foot here is complaining her shoe is a little big for her. Also, I thought that I should have a change in shoes. Flats are getting too boring for me so I thought why not get heels? And it's not just kitten heals, but really high heels!

However, I swear to anybody, my feet ached like son of a bitch after a day of tip-toeing in a pair of new and stiff shoes. Wearing high-heels is tip-toeing while walking around. The shoes are comfortable in a way that it doesn't give me blisters but it's the soreness that's bothering me. I believe the way I'm walking in those "stilts" are wrong such that my back will ache after walking in it for awhile. That's bad, isn't it?

But one thing I noticed after looking in the mirror at my legs when I got home to make sure they aren't deformed after a day of walking in those heels, is that my bowed legs aren't as bowed as it used to be. Yes, I do have bowed legs if you guys didn't notice and I really hate them. Perhaps it's just me, but it seems my legs aren't as bowed before. If that's the case, if pumps could really close up the bowyness of my legs, then it's pumps for me everyday! :P

It may harm my curved spine though. :/

OH! My bones have these deformities; bowed legged and curved spine. I think I was a regular milk-drinker when I was young. So why is it that my bones did not form properly?!

Ah.. perhaps I may develop a love for pumps if my own pair doesn't give me troubles! ;D
