Replying to Calling all boot wizards (Lange boot issue)

Hi all,

I just got a new pair of Lange RX 120s (yes they were fitted and yes there are custom footbeds in there. They felt great at the shop, but the minute I take them skiing, they're awful. Anytime I go extra front seat (whether it be because of a forward landing, hitting some soft snow, or being forward to ski down something steep) my heel gets slammed so hard into the back of the boot. Specifically, the region from the achilles outwards on both heels. It feels like I flex into the boot and then once I hit a certain point, the forward momentum of my shin is transferred to my heel jamming into the back of the boot, causing quite a bit of pain (Ps the boots are definitely not too big. It feels like it's more the design of the boot than the actual fit).

I looked around online to see if anyone else feels this in Lange ski boots, but I was surprised to not come up with much. It's so strange....they don't ski like most boots.

Am I crazy or can anyone attest to Lange boots specifically skiing like this? If so, what part of the design of the boots causes this? Is there anything that can be done at the shop to fix this?

Thanks,
Ethan
