Yup, I pulled the laces tight and strapped them in. The only thing is the heel is quite tight and they don't sit all the way down and back without considerable force, e.g. standing in them.
I think when you are on the snow and have the board tilted, you should be able to tuck your heels into the heelcup more snuggly. I've noticed many times that it's harder to get the boots all the way back into the heelcup in my living room.
