This refers to court shoes (flat soled shoes designed for sports
like tennis) which became a fashionable item for the "casual"
subculture of football terraces - in England - during the late 1970's
and 1980's. The genesis of the culture and it's fashions are believed
to have been the result of Liverpool fans bringing home fashions
from continental Europe after their European Cup games of the late
1970's. The casual subsculture and it's fashions have been popularised
by movies such as the remake of The Firm (2009) - starring Paul
Anderson. The terrace shoes which proved to be the most iconic were
made by Adidas: such as the Adidas Munchen, the Adidas Trimm Trab
and the Adidas Gazelle.
