Opinion on these sandals for a guy?

I love wearing sandals and I’m lucky I live in a location that’s warm year round. (S. Florida) I saw these Birkenstock Kairo model and really like their style. —>

I’m thinking of getting myself a pair of them in black. Would these look good on a guy why/why not?

constructive criticism only, please.

If link to them does not work, just google “Birkenstock Kairo” not the woven kind, but the plainer ones.

Thanks.
