Loads out there, all prices. As regards 'waterproof', that in itself might present you with a problem? I've bought 'waterproof' boots in the past, one pair leaked from the word go, another leaked after a few miles, others have never leaked. My personal view is and I'm not even suggesting that I'm correct, but from personal experience, your best chance at purchasing 'waterproof' ones, is to only go for full leather type versions.
The full leather ones I have purchased, first from Brasher, now taken over by Berghaus have never leaked, the highly stitched and patterned fashionable looking ones that I bought, have! That's my experience, I'm sure it may not be other peoples experience.
At present I wear a pair of Berghaus Superlight 2's and am very satisfied with them.
