Sandshoe

According to the Eleventh and War Doctors, the Tenth Doctor wore sandshoes. (TV: The Day of the Doctor) He himself generally called them trainers. (TV: Time Crash)

Behind the scenes
"Sandshoe" is a primarily Scottish or Australasian word for a sneaker. The implication in the scene is that the Tenth Doctor thought they were shoes meant for running, whereas his other selves thought they were walking shoes.
