Replying to Ski boots`

I am having a real problem finding a good boot. I have crappy race ones now and I have been trying on alot of different boots trying to find one that is easy for me move around in. 2 years ago I had kid boots and I only weighed 110 and only 5'4 now i am 5'11 and weigh 140. I have the hardest time one jumps. I don't have enough weight to get my skis around and I feel my boots are the problem. Anyone recomend a boot or a way to make it easier to get my skis around?
