Dave Cowens' felt-green Tigre's that he wore in the mid-70's were the coolest shoe ever worn by a Celtic - they were both unique and great looking.
back then, i had a pair of the low-cut green adidas worn by Havlicek and Russell, a pair of Charlie Scott green Nikes and some pro-keds like Jo Jo's that were black, not green. i was a teenager and i worshiped those guys.
