Propa Liner Sleeve
End heel lift. Lock in the fit you already own.
The Liner Sleeve is a clean, precise way to tighten your boot fit and bring heel hold back, without permanent changes or complicated fixes.
Designed to slide over your existing liner, the sleeve applies targeted compression through the rear of the boot, reducing unwanted movement and improving stability.
Instead of replacing a packed-out liner, the Liner Sleeve brings your current one completely back to life, adding security, improving control, and extending the usable life of your boots.
Optional foam inserts allow you to fine-tune support around the heel, ankle, or instep, so you can address looseness exactly where it shows up.

Fit note
The sleeve increases compression through the rear of the liner. For many skiers, the improvement feels immediate. For others, the foam may take 1–3 ski days to settle as the liner beds into its new shape. Give it time to adjust - the payoff is worth it.
Compatibility
Not compatible with ZipFit or injected liners.
Sold as a pair (2 sleeves).
