Replying to Waxing New Skis?

So I just got new skis for the first time in like 6 years so I was wondering if I need to wax them before using them for the first time? I've been using the same pair since senior year of high school and I can't remember what I did back then when I got them. The bases seem pretty smooth right now, so I feel like I could go out a couple of times and then wax them, but I don't want to get out to the mountain for the first time and not be able to move.
