I have skied these less than 10 days. Bought last year in the late spring. Molded professionally once obviously. But can be molded again or skied in to mold over time. I'm moving down a boot size which is why I cant use these.
The best part about these liners is the cork padding. They are not foam they are cork meaning they have twice the lasting power of intuition liners. Rumor has it about 500+ days before they're done.
Also because of the design and padding your ankle is not going to move. You will feel secure and comfy these puppies.
They have the have the zipfit booster strap still and the lace up zip tie secure lock if you want them tight.
