SheikhAukthank you onenerdykid for all your hard work and amazing advice ! Question from me: When I was sin Chamonix last time I wanted to buy new boots. I went to two reputable shops. I got fantastic service but despite me asking to try one Atomic XTD 120, i was told the boot is not for my kind of foot- norma wide last 100mm. When i spend money on a ski boot i want the highest quality and one of my primary choices was Atomic. I ended up with dalbello lupo ax 120 with custom liner (sidas crt) and footbed. later i found out dalbello uses IRFRAN plastic to make their boots. it is apparently inferior, cheap plastic? not sure if it is true. does the use of plastic depends on boot construction /desig i.e overlap- grilamid, three piece shell-Irfran? Can you comment what tech Atomic uses and why not Grilamid? thank you.
Thanks for the kind words :)
First, it's definitely possible to widen a Hawx Ultra XTD by almost a full 10mm, so depending on your actual foot and its actual "high-volumeness" it should be quite possible to fit a medium volume foot into that boot.
Second, I don't want to throw any hate towards Dalbello, but Irfran plastic is a type of polypropylene, so it is a cheaper type of plastic. It was probably selected because of it's light weight properties (and it's cost effectiveness too) but it comes at the cost of durability- this plastic is not as durable as PA (i.e. Grilamid) or PU. It might ski well in a 3-piece design, but you should keep an eye on shell wear and tear.
We definitely use Grilamid in our boots- there are multiple versions of Grilamid (it's a range of plastics from EMS Grivory in Switzerland) and the ones we use we like very much. The Hawx Ultra XTD 130, 120, and 115W use Grilamid and so does our forthcoming boot, the Hawx Prime XTD 130 and 115W.
