You could rent your all-mountain skis every time you head to the slopes but the issue with that is that it can get quite expensive. To rent skis runs you a little bit of money as you have to rent the boots, helmet, goggles and all the other gear to get you safely down the mountain so it is best if you enjoy skiing and will be hitting the mountain a couple of times this year to buy a pair as it will be cheaper in the long run.
