Unanswered Question

Sweaty Feet: I have these boots from several years back. Love everything about them. Except... My feet sweat horribly. Even with antiperspirant. At the end of the day, I pull the custom intuition liners out - they are wet on the inside, AND the outside, as is the internal area of the shell. Sometimes there is even snow in the shell, or perhaps frozen sweat? Anyone have any suggestions?

Im finding for alpine soles for Dynafit...

Im finding for alpine soles for Dynafit Zzeus and Gaia. I think its the same with alpine soles for Titan. Do you know where I can buy it?

Write your question here...I ski a Lange...

Write your question here...I ski a Lange 28.0 with sole of 323mm for an alpine boot. Will this Dynafit work in a 28.0 as well??

Hey Todd,

Thanks for the question. When it comes to the sizing on the Dynafit ZZeus TF-X Ski Boot - Men's, the sole length on the 28.0 will come out very close with your Lange so you should be set length wise. Width wise, you should be good too unless you have a Lange that has a flex of 100 or less, then it'll be a bit narrow as the stiffer flexing Lange boots are usually narrower in the forefoot. I hope this information helps.

i've tried dynafit zzero 4 and they fit just great, they are like a glove.will dynafit zzeus tf-x be the same or better or...? i have a narrow foot, low arch

Is there a marked difference b/w this boot...

Is there a marked difference b/w this boot & the more expensive Titan TF-X? ie. would I get a lot more out of the TF-X?... I intend to use either of these boots with Dynafit bindings & Black Crows Corvus 175 skis (135-105-126) - backcountry set up for Australia / New Zealand. Thanks in advance...oh, I weigh 75kgs & ski fairly aggressively, 35+ years skiing. Thanks again :-)

Best Answer

The biggest difference is stiffness. Although I hate to use them as there are no standards, the flex index for the Titan is about 120-130. This Zzeus is more like 100-110. Your decision will depend on what you're used to (what you like), how aggressive you ski and you in-bounds vs. out-of-bounds mix. Hope this helps.

Sandy> I'm 209lb heavy guy and prefere skiing 60% resort, 40% backcountry/freeride, my set is Line Prophet 100 + Marker Baron and want to go in ZZeus. Will they hold me in every situation - in resort it doesn't mather but in downhill/powder because I heard that they are not som stiff due to that new shell material which change it's stiffnes according to temperature

Can anyone tell me how to adjust the forward...

Can anyone tell me how to adjust the forward lean on these boots. I purchased the Zzeus recently and can't seem to figure out how to adjust the lean to 21deg as shown in the spec (show forward lean 15-21deg)

No tools needed. With you foot in the boot, place the boot into walk mode and flex forward hard a few times. Switch into ski mode and stand up gradually. You will hear (and feel) it click into the forward position (21 deg). To set the more upright position, switch into walk mode and straighten up. Then switch back into ski mode and flex forward. It will lock into the 15 deg slot. Enjoy!
