How can i make my large Calves smaller?

I have been a dancer for almost 22 years! This has caused me to have very large calve muscles, i taught dance for almost 5 years and i have recently had to quit for a while. Recently my Grandmother bought me a beautiful pair of madden boots, up to the knee. The problem is they do not fit which made me go out to find another pair and surprise! I can't find a pair that will fit above my ankle! In the past year i admit i have gained some weight, health problems have made me quit exercising as much but my calve muscles have also stayed large. My question is what can i do to reduce the size of them? I want to be able to wear cute boots above my knee. any help or advice is appreciated!
