Hello! These are EUC ski boot inserts (believe these are tecnica brand) with Sidas insoles. (First pic is from Amazon for the Tecnica Zero G Tour Ski Boots 2021 and not actual liners you’ll receive). PLEASE NOTE: Cannot find sizing on boot liners. See measurements.Insoles are size large. Per the Sidas website, large insole fits shoe size US 9-10 (see pic) Thanks!Let me know if you have questions:) *first pic is stock and is for representation only and not of the actual item*
