very low heights

Very cute shoes made for walking -you would think. But I do preffer to feel taller than what I'm. I would really preffer a 2.5" heel....why is this height soooooooo difficult to find, WHYYYY! this would be prrrrrrfect if the where that height. All shoes are either 4" or 1"....the 2.5 is so rare unless they are boots.
