I've been wearing Bauer Vapors (I forget which model) for the past two years, and haven't had any issues with them. I didn't mould them at all but if new skates tend to give you blisters like they do for me, I suggest a Superfeet Yellow Insole from Sportchek

I have them in my hockey skates and in my roller blades and have not had a single blister issue, they're expensive, but they've been worth it for me.
