Dynafit ZZero 4 PX-TF Alpine Touring Boot

With its more-forgiving Rislan PowerStringer, the Dynafit Zzero 4 PX-TF Alpine Touring Boot offers all the comfort and fit of Dynafit's C-TF model, without the carbon reinforcements. Tackle long tours and sidecountry trips alike in this four-buckle boot. Touted as the lightest four-buckle on the market, the Zzero 4 PX-TF boots grant featherlight uphills and rewarding downhills. Mid-stiff Rislan material in the instep and Powerstringer efficiently transfers energy to your glides as you hike and hold firm during sketchy descents. The Zzero PX-TF Boot's Pebax tongue flexes smoothly and consistently as you pass your skin track on the way back down, and Dynafit's lightweight, thermo-moldable Thermoflex liner insulates your foot so your toes don't end up frozen at the end of your hikes.

Bottom Line: The Dynafit Zzero 4 PX-TF Alpine Touring Boot climbs easy on the skin track, and skis hard on the descent.

LIMITED BACKWARD CUFF MOTION

By: Anonymous(1)
January 31, 2008

Compared to similar Dynafit-compatible boots by other brands, these boots seem to have limited backwards cuff motion in tour mode. The result is that you can't stand up straight in them while skinning, and your weight ends up being carried by muscle tension instead of your skeleton. This is subtle and may only matter for those who do very big days. In terms of weight, construction, and ski performance, the boots are excellent.

How do you mould the liners? Stick them in the oven? At what temp and for how long? Then what?

what ever you do, be very careful - no info came with my boots, and after web research went conservatively to 230deg in convection oven - and they self destructed after 8 minutes!

Can AT boots be used with conventional alpine bindings?

Can AT boots be used with conventional alpine bindings?

yes but the alpine binding won't release normal. The rubber sole prevents the Alpine din from being accurate so you have to do a bit of trial and error to find the right din setting. I would not recommend skiing alpine bindings with AT boots but it can be done.

Dynafit Zzero 4 PX-TF Alpine Touring Boot

By: JeanPierre(1)

Hi! I am French and I live in Maine, so forgive my English. Those boots are my 5th Dynafit AT boots. I usually prefer light weight for long trips and an easy uphill. I began to ski when I was 5 years old. Those boots are the best I have ever had: still light, but more rigid than the race models, very comfortable uphill, and hot. They are clearly softer than the carbon model, but I think it's a perfect compromise. I have wide feet, so I had to choose 29 instead of 28.5, because they fit a little bit more narrow than the other Dynafit I had. Its downhill skills are far better than all I have seen before in the brand. Conclusion: they feel rather like perfect all abilities touring boots than pure freeride.
