I traditionally have worn Roman style sandals but they are very flat so I’ve been wearing my Burkes more since my ankle surgery
I just wear sneakers in the summer. I got my Birkenstocks in the fall so I haven't gotten much use out of them so far. Crocs are for indoors/the beach/my yard only.
Flip flops are only acceptable at the beach. I go with Huaraches like a gentleman though. I don't think dudes can pull off open-toed sandals in general. Put your graspers away, no one wants to see that.
