Where to buy football boots

Just moved here from the states and all I brought with me where my studded football boots. Unfortunately, these do not work well on the turf surfaces here, so I am in need of a new pair. Does anybody have any store recommendations? I have been to Karstadt Sports at the Zoo, but their selection is limited. Are there any football specific stores in Berlin that has a larger selection?

Thanks

I would say Karstadt maybe a good bet - they have a good selection in Alexanderplatz, and the Zoo branches - along with Trikots, even Manchester United believe it or not!

I alos would have thought Karstadt Sport would be a good bet, if not then try the sports floor of Galeria Kaufhof in Alexanderplatz.
