Too casual to be shoes - definitely not trainers as no sport could ever be undertaken in them.
Usually in two-tone brown, often slip-on or velcro, always ugly.
Can be seen on dress down fridays or family holidays as dad thinks they will be good for the pool in the day and the restaurant at night.
"You could always wear shrainers like Patrick does?"
"I'd look less of a dick wearing shoes!"
"Right kids - who's ready for the disco?"
"Dad. I'm going nowhere with you if you're wearing your shrainers".
