Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'внешняя подошва'. The standard Russian equivalent is 'подметка' or more technically 'наружная подошва'. 'Подошва' alone is ambiguous (can mean the whole sole unit).
Common Mistakes
- Confusing 'outsole' with 'insole'. Using 'outsole' in general contexts where 'sole' is sufficient. Misspelling as 'outsoul'.
