I am not sure about that, for the following reason: The boots make or brake the alpine deal. Your boots need to fit, and fit well. Otherwise you will suffer, no matter how much money and training you invest. Hardboots are expensive, and if the boots you buy turn out to be the wrong shape, you may have burnt a few hundred Euros.
I would therefore recommend, as a first step, to determine which hardboot shape is best for you. There are only three to choose from (unless you want to spring for Mountainslope right away): Deeluxe symmetrical, Deeluxe asymmetrical and UPZ. If you find a pair of, for example, UPZs for half their new price and like them, you can still unload them on someone else for more or less what you paid and get new UPZs. Or you keep them and just replace the liners.
If not, rinse and repeat with Deeluxe.
Also, don't forget the all-important shell test. Too large boots are a very common source of beginners' problems. When you first get the boots, take out the liners. Step into the shells so that your toes touch the front inside. You should be able to fit 1-2 fingers (lengthwise!!) behind your heel. If there is more room, get the next smaller shell size.
