Kangaroo shoes

Most people are familiar with the comfort of a pair of true leather shoes which have stretched out to fit the contours of their feet. Adidas looked for a material that had even more give than the leather from cows and found it in kangaroo skin, used in their new top-of-the-line soccer shoe, The Adidas Predator (the shoe worn by the English
national hero, David Beckham, midfielder for Manchester United and loving husband of one former Posh Spice).
I would bemoan the use of kangaroos in such a manner but it turns out kangaroos have few natural predators anymore and are in no danger of extinction.
I'm surprised there are still any animals left which the fashion industry hasn't already exploited in some way. I wonder if we'll be wearing kangaroo leather pants and kangaroo dress shoes in a few years.
