These Wintersteiger insole shims are thin, precision-cut inserts used by boot fitters to fine-tune volume and fit inside ski boot liners. This pair is sized 1/16" thick for boot sizes 10/11, helping dial in a snugger, more supportive fit. A quick, professional-grade fix for boots that run slightly large.
