Best cyclocross bike under £1000 and other CX chat

Can any one recommend the best Shimano shoe for cross?
wanna stick with Shimano as heir 43 is a perfect fitfor me, want grippy sole, top buckle and some flex....and no too expensive.

I went for the XC50N.

Basically, they're the same as the XC50s, but with the mesh bits covered up so you don't get soaked straight away.

I don't think the sole is super grippy though - maybe it'll wear in a bit? You can add studs if required.
