Buying Soft Bindings
Unlike many pieces of boots together. Your ultimate goal is to find the best fit and you want to make sure that the two pieces work well together. I rode a snowboard very uncomfortably for two seasons before realizing that my boot was slightly oversized for my bindings and the straps were smashing down on my boot and crushing my foot. If you can, speak to an experienced sports equipment retailer for good boot/binding combinations.
It's also a good idea to find out whether your bindings will even attach to the three. Find out which set up your board is made for and plan accordingly.
Finally, it pays to look at snowboard equipment review sites and find out what professionals and amateurs recommend. Taking a little time to read people's opinions often pays off greatly when it's time to purchase.
