Trainers

Reebok workout was one of the first non-skateshoes to be used to skate in...early 90's. Also the shoe of choice for all gangsta-wannabe's (Kareem Cambell, Menace team....some of whom were and still are ganstas). Palace have totally gone down that route with their appeal, so an 'official' workout to skate in makes perfect sense to me and its actually pretty credible. Nike, Adidas, NB, etc all have their own skateshoes so this makes perfect sense to me,

You're right about the Workouts/KCK thing, although Reebook Workouts were hardly the first non-skate shoes used for skateboarding... Skateboarders have always used non-skate shoes for skateboards: dunks, clydes, even before the 90s I think.

By the way I just bought "Made for Skate : The Illustrated History of Skateboard Footwear" and it's a very interesting reading, including a discussion about this Animal Chin/Jordan thing...
