toe lug - / təʊ lʌɡ / -
noun
The front part of a ski boot shell that connects into an alpine ski binding. These lugs must comply with industry standards for quality and dimensions. In the majority of cases they are an integrated part of the boot shell but higher end boots are more likely to be replaceable in the event of wear.
\\ My toe lugs are shot from hiking up and down main street. I swear they won't fit in my bindings soon.
