Don't I need the most recent model year?

Only if you need to keep up with the Jones's.

The truth is most products are the same as a prior model year except for a change in color or graphics.
Some years there is no change at all.
A useful evolutionary idea does not come along every year. So how do manufacturers get you to buy new model years season after season? They change graphics, lingo, and tweak with minor modifications that are better left alone.
There are some big deals. Shaped skis are a big deal. There is no reason to ever ski on a non-shaped ski, and in fact, except for a few mogul and DH skis, there haven’t been any 'straight' skis made in the past decade.
Heatfit Boot liners are a big deal. They provide a more comfortable fit and personalization.
Free-floating bindings (aka railflex) are sort of a big deal.
But in all honesty a quality new product from 3 years ago will be equal to a quality new product today and in many cases may exceed it.
We provide plenty of information about every product we sell so that you can be sure that you are getting a product that is right for you.
