Now we're talking! I have an absolute boot fetish, think I have close to ten pairs at the minute - plus I get through five games some weekends so I don't have the chance to wash and dry them between games..
Best I have at the minute are Adidas Copa
LINK (not exact ones I have as doubt can get them any more), very comfortable, super easy to clean and are holding up well.
Lots swear by the classics - Adidas Copa
Mundial, Nike
Tiempo etc. I have new Nike Phantom
LINK in all black that cost £240 and are easily the most comfortable item of footwear I've ever worn, but aren't easy to clean and are expensive (I still play and got them cheaper, don't judge me!).
Plenty of blackout boots available at the minute that look the part. For soft ground I use Nike Premier
LINK, these are a really good boot and I'd highly recommend them, the anti-clog really works too.
Finally, I'd recommend not spending less than £50 on boots, unless you know of a certain cheap boot that will be suitable. Look for recommendations and reviews and go from there.
