About Dynafit 04U Ski Boot: Hey this is Tim from Dynafit. I’m here with the 04U. This polyurethane boot offers a lot of power. Polyurethane is what boot-makers use to make alpine ski boots. Polyurethane puts a lot of energy transfer into the shell, so you’re not only able to drive a big ski with a lot of forward flex support but you rebound back out of that turn. So it’s like a well tuned shock on a mountain-bike. So take note of the 04PU Polyurethane. It is the best bank for the buck in ski boots. Comes with all the features like the quick stepping insert, magnesium buckles with the tour latch key, great ski walk mode, full Thermoflex liner, and a big tall powerful boot that is still lightweight enough to tour all day in the back-country. This boot is maybe ideal for in and out bounce terrain.
