Just picked up a Pair of new Nike ACG trainers. 49 quid at all good sporting outlets!!!
They come either in Black N Grey or Blue N Black. They have a rugged sole which has 1.5 cm(ish) teeth all over it. They fit pretty snug and are as comfortable as most running shoes. Used em at Sparklies and they also seem to be fairly water resistant. They actually look very similar to the Dye ones! but I think these are cheaper.
i wear digger x-tream cleats for outdoors and a pair of nike trainers indoors or on hard ground.....got my boots from planet ages ago...think they have something similar on special at the mo tho
