About Dynafit Zeus & Gaia Ski Boots: Hi, I'm Tim from Dynafit, here with the Zzeus and the Gaia. Dynafit's boots are made in Montebelluna, Italy, legendary boot making valley deep in the Dolomites. Dynafit's boots are Alpine overlap construction. What that does is it gives you a true Alpine ski boot performance and fit. So you're locked right in snug on the downhill, but as soon as you decide you can't handle skiing with hundreds of others on the lifts, you can flip it into tour mode, put your skins on, and off you go into the back country. The Zzeus and the Gaia are also the lightest boots in this Alpine overlap category. Call it what you will. Call it slack country, call it back country. It is your free choice of where to go in your own lines. We call it free ride touring, because there's no free ride to the top.
