Pehmustettujen
Pehmustettujen is a Finnish grammatical form derived from the adjective or past participle pehmustettu, meaning padded or cushioned. It is the genitive plural form used with a noun in the genitive case, typically in constructions that express possession or a description of a group of items. In Finnish, adjectives and participles agree with the noun they modify in number and case, so pehmustettu becomes pehmustettujen in the genitive plural when describing plural nouns such as kenkien or suojavarusteiden.
The form is common in descriptive or technical writing, product catalogs, and contexts where the padding feature
Etymology-wise, pehmustettu comes from pehmuste (cushion, padding) with the past-participle suffix -ttu, yielding a describable property.
