In reply to Philip:
Thinking about it, dont take my advice ive already written, whats good for one person isnt necisarily good for another. My boots are great for my feet, but my feet are probably hideously deformed yours may not be.
Listen to peoples advice on build quality and price, but dont listen to the 'oh, they made my feet bleed' storys, as everyones feet are different just the same as their walking style and weight distribution.
(This isnt saying that all these peoples opinions arnt valid though)
I recon you should try on every boot in the shop classed as a B2 grade (winter wallking/alpine/easy climbing boots). See which ones are comfortable (and dont be affraid to march round the shop for a full hour, as its a lot of wanga youre spending). Then buy em.
