Used approximately 30 times. Due to interference with the highback, the cushion part of the heel cup is slightly worn (see photo 8). Includes genuine titanium screws. The S size is for boot sizes 22.5cm to 25.5cm, but I think it can be used without problems up to 26.0cm. Carbon is incorporated into the materials in various places, making these bindings lightweight and highly responsive. Although there is little deterioration, these are gear that has aged, so please consider purchasing with that in mind. Thank you for looking.
