What boots should i get i know nothing

I got these ski's, Blizzard Thunderbird Sport r14 ti, in 160, and I need boots, I'm a size 10.5 US men's and I have no idea what boots would go well with these or are good in general, I ski on east coast and I'm fairly casual no problem with any black or double blacks I find here. im just trying to keep the price under 400 if possible
