Replying to Help with my ski boots

OK, first off i have Dalbello Aerro 70 ski boots (i think) in size 32.5. When i first got them 2 winters ago i had no idea what i was doing with skiing and i probably bought my boots wrong. i just remember trying to get the boot on and after struggling forever i gave up. but now my boots have loosened up so much. For instance, my top three brackets go almost as tight as they possibly can, and my toe bracket comes off on its on and can't get tighter. Also my foot inside moves way to much for it to be good, my heel will come up if i put pressure on my toes and there is a lot of wiggling that goes on.  And lastly, near the tip of my toe the rubber piece that is wedged in under the flab that you tighten towards the boot falls out constantly and i have to shove it back in. Does anyone have any suggestions other than buying new boots because i do not have the money to do that. :/
