Olympus Mons / Spantik Innenschuh-Schnürsenkel

My inner boots finally feel like they're holding my foot again—these are the exact right length and thickness for the Olympus Mons liner, and the eyelets get a snug, secure lock that my old frayed ones lost.

Fitting these into the inner boots was straightforward since they’re cut to the exact original length, so no extra trimming or fiddling with the threading. They hold a knot securely through a full day of climbing and feel just as sturdy as the factory pair that finally wore out.

I was worried the inner boot laces wouldn't hold up at altitude, but these feel just as sturdy as the originals and the length matches perfectly for threading through the eyelets. Slipped right in with no fraying, so my boots are finally ready for the next climb.
