http://www.centralsports.co.uk/shop.php?page=forza There's a few FZ Forza shoes on the Central Sports website; I don't know if they have the particular model you want but it's at least a place to start.
Like i have said before, a list of Forza Uk retailers can be found at http://www.forzabadminton.co.uk/retailers.html ... central sports no longer deal with forza and dont have the latest gear in ... The FZ 808 can be recommended, they are great value ...
