Absender-Einlage

The Primaloft insulation in these replacement liners made a noticeable difference on my last dawn patrol—my feet stayed warm even in single-digit temps. The fit is snug right out of the box, which I appreciate since I don't always have time for a heat-molding session.

Finally got these liners heat-molded and the difference in heel hold is night and day compared to the stock ones. They're noticeably warmer on chilly morning starts without adding any bulk inside the shell. Exactly what my feet needed for longer tours.

Just installed these replacement liners into my Sender boots and the difference is immediate—way more snug around the heel than the original pair. They warmed up noticeably faster on a cold morning tour too.
