If you want same footer on all pages, then choose any footer as per your choice from ‘Theme Options > Footer >Default Footer Template’ (Figure-1) and choose ‘Theme Default Footer’ from page level (Figure-2) and this is not applicable Shop related pages.

If you want different footer on any page, then go to that page and choose any footer except ‘Theme Default Footer’ from ‘Select Custom Footer’ section.

As layout for ‘Shop’ related pages is managing from Theme Options only, so you won’t be able to edit those pages through ‘Elementor’ and can’t choose individual footer for those pages from page level. You can choose footer for those pages from ‘Theme Options > Footer’.
