In reply to Dylan:
Anything in the 130*100 size range. Moon warrior, ocun moonwalk, snap bun, etc etc.
Metolius or Organic if you have a narrow boot (they are 3 ft wide rather than 100 cm).
See what you can get a reasonable deal on, say £130-140 if you shop around.
Edit: that price range doesn't apply to Organic!
