Buddha was giving a few links about this subject a while back but in the techroom I think the Post Title was Footwear
As you have said you see players wearing american shoes well, most of them got them from the states either by mail order or by going on holiday there (or getting some one who was going to bring a pair back). Tony at Maxem is selling the new and improved Tanels (very expensive though, no offense Tony good they may be but they are a lot of money)
Look for sports discounters online based in the states, you will have a delay cos of shipping but that will be the cheapest way.
Steve Bull also sells the type of shoe you are looking for his number is 07000 8633726837 ( I know that looks too many numbers but it spells UNDERCOVER)
Decide also what height you want low ankle is not good but you may prefer that again look for the thread called Footwear,another thread around the same time was called something like "what do you wear when playing"
