Hockey skate fitting?

Im having trouble finding a skate that fits me right. Ive tried on a couple different brands and models, all of which my toe was touching the end, but i can still wobble the skate from side to side. Ive watched other people try on skates and ive noticed that none of them can move their foot (more like ankle/right above the ankle) side to side. I dont want to buy skates if im going to have this problem because i have rollerskates, and my current ice skates and its annoying and i feel like its putting me at a diadvantage trying to position my legs correctly for different things. Any suggestions?
