Outsole RPS3

Bought this as a backup for my Spitfire 2.1s and was surprised how easy it was to swap out the old sole. The fit is perfect—snaps right into the boot without any trimming needed. Really extends the life of a great boot.

The rubber compound on this replacement sole feels noticeably more durable than the original—I've already got a few days of icy approaches in and the tread pattern is still sharp. Took about fifteen minutes to swap with a heat gun, and the fit is perfect.

Installed these on my Spitfire 2.1s and the fit is perfectly snug, no trimming needed. Grip on icy patches feels noticeably better than the old worn-out originals.
