When I first started riding, I got a pair for Nike Mowabbs... er they were crap, so my regualr shoes were Nike Air 180's, brilliant! (still have em too)
After soem Shimano M051 and M110, I went (and still have) Answer Accelerator (II), Nike Yuha Plus, Nike Cairns (orange still go strong, Red lasted 1 ride) and Now some Sidi Eagle 6. If the Cairns wernt so narrow, they'd be the best shoe EVER.
