Comments

  1. I know from personal experience that the plastic portion of the lower shell on the Alien 1.0 can be stretched — and more importantly, hold the stretch w/o any rebound.
    Skimo Co says the Syborg is Grilamid so should work for a skilled boot technician.
    I know that the 2015-16 TLT6 Performance (in black) switched to Pebax. But the older white & blue PDG was supposed to be Grilamid, and the black & blue 2014-15 is listed as Grilamid by Skimo Co, and I haven’t heard any changes for 2015-16. Plus if it had changed, sure would have bumped up the weight, and the spec is still the same.
    (The TLT6 managed to stay about the same b/c the heavier lower shell was compensated for by switching from the heavier CR liner to the lighter CL liner.)

  2. Robert – the lower boot on both the current PDG and Syborg are grilamid, which generally responses well to punching. You may be thinking of the new (black) TLT6 which is now pebax (formerly grilamid in the green TLT6 and TLT5). Pebax is more difficult for boot fitters to work with/punch.

  3. Thanks jonathan about the comments on half sizing. I didn’t know about the 2X.5 and 2Y.0 shell being identical for those boots.
    Another query I have, can all of these boots be heat punched?
    I heard the new Dynafit PDG are made with pebax, so not so easily heat punched? And can the syborg be heat punched?

    Thanks!

  4. I’ve also heard the same about the Syborg being wider and/or higher volume (even if the official stats seem to indicate otherwise), and it worked out for a buddy who bought it for that reason (although his size is way too big for me to do a side-by-side comparison w/ my boots).
    I can confirm that with my feet in the shells of a 26 Alien 1.0 and a 25.5/26.0 EVO, the widths seems identical.
    By contrast, the shell of a 26 RC1/Ultimate/400 is way wider in the forefoot.
    Somehow though the boot has been fine for both skinning & skinning – the instep is fairly low, so combined with the laces, must be snugging up my foot where it counts for actually controlling the ski.
    But of course that boot would be an even bigger leap of faith and financial commitment…
    Also, for any of these boots – whether skimo race, ski touring, alpine downhill – half sizes are a complete fiction, but the shell break varies by model. Both Syborg and EVO/PDG have 2X.5 and 2Y.0 as identical, although that differs from other Dynafit models (e.g., TLT5/6 has 2X.0 and 2X.5 as identical).
    So if you try on a different half size in the same boot, you might be trying on a shell that differs by about a full cm, or the only difference might be a minor liner tweak that will disappear upon any use.
