In many stores you can ask for "test skis". These would have been used for a few weeks as rentals and you usually get a significant discount from the normal retail price

You also get 'test bindings' that both toe and heel can be shifted forward/back to adjust to fit most boots. Disadvantage: weight. Advantage: adjustable.

On normal bindings the toe is often screwed in at one location to fit your boots and cannot be shifted later.
