I did some research on Romulans from the movie Star Trek and I came across this bit of interesting information:
Chameleon-esque "Capote" actor Clifton Collins steals several scenes as Nero's second-in-command Ayel — but his alien costume had to be tweaked due to a real-life abnormality. "We had to make some modifications to my wardrobe that people may not know," he revealed. "[The Romulans] have feet that are broken up at the big toe. But I've got webbed toes on my left foot. So I couldn't wear the Romulan shoes. They had to fake it, and put in a little toe insert."
