Recommend me some new trainers

[LimaDelta]

I travel a lot for work, and like to pack light. My old Nike Free are finally ready to be retired and I am now playing a lot more 5-a-side on artificial grass. Also like to get out and walk a bit, and not look like a knobber. I am therefore looking for a good pair of all-rounders. Support for a neutral running style, enough grip for the occasional muddy trail and to stop any strained groins on the pitch. Any suggestions? Trail running stuff seems completely unsuitable for football, and vice versa. Cheers!
