Shallots overwinter in New England?

Hey all, I'm curious if anyone has experience planting shallots in the fall to overwinter in New England or a similar climate (6a-6b). I'm in the Boston area so we get cold winters but they're not brutal and I have some friends who grow garlic over winter with great success. I've read that shallots are less hardy than garlic but I don't really have any experience with root vegetables over winter so I have personally no clue!

I'm planning to try growing them in a raised bed and could potentially put row cover on them if that changes things.
