Cute thick/platform yoga sandals
The straps aren't super reliable, sometimes it just draws them as flip flops. More accurate with close-up shots. You can also add foot-related tags to direct the AI's attention toward the feet, even in far-away shots, and get more consistent straps... sometimes
The trained word/phrase is "s4nuk sandals" but you might also need to add "sandals" as a separate tag to get them to show up.
The real sandals are 5cm thick, recommend adding "platform footwear" tag if you want that appearance. Otherwise they usually show up flat.
