1. FITS ALL ALPINESTARS BOOTS THAT REQUIRE A SCREW
These sliders are model #25SLI510. (Sometimes written as 25SLI5-10.) They are marketed as replacements for Alpinestars Supertech-R and SMX-Plus boots but also fit Alpinestars SMX-S and SMX-6 V2 boots (both of which I own).
SMX-S and SMX-6 V2 boots come from the factory with plastic sliders which wear out very quickly – like within 2 or 3 sessions during a track day if your toes touch down often. But the sliders offered for sale in this listing are made of aluminum, making them much more durable.
Rest assured: All four boot models I mentioned use sliders that are the same size and shape, and use the same mounting tabs and screws, making the sliders completely interchangeable.
