The conversion belongs to this title
This is one item described with two audience-specific size numbers. A women’s 8 label here does not establish the same fit as a women’s 8 shoe from another brand. Nor does the men’s 6.5 number tell you how much room sits above the toes. Check the seller’s actual measurements and selected variation.
Compare a color change separately from size
The black-pink women’s 8/men’s 6.5 listing has matching nominal numbers but a different product image. The supplied information does not prove whether its shape or materials are otherwise identical. Ask before transferring a successful fit or protective specification between them. If shopping only for a size replacement, the two neighboring all-black entries are clearer reference points, though the manufacturer identity still needs confirmation.
