Frankly, I find the "poshboots" simply hideous, not to mention they look extremely uncomfortable. We aren't suppose to just walk on the balls of our feet.
As for those high, high heels; sexy, yes. They make your legs appear shapely and give a short woman the stature she craves. (or in amber's case that amazonian feeling hehe).
There's something worse than sore feet, though and that's the irreversible damage to the spine, that wearing stilettos causes over the years. So have fun wearing 'em now, but be prepared to pay for it physically eventually.
