However, you could use a descriptive phrase like:
* "Kūpāʻau keʻokeʻo" - This literally translates to "white foot" but implies the toes are white as part of the whole foot.
* "Nui ka keʻokeʻo o nā manamana o kona wāwae" - This means "There is much whiteness on the toes of his/her foot." It's a bit more verbose but emphasizes the white toes.
Ultimately, the best way to convey "white toes" in Hawaiian depends on the context and the desired level of formality.
