I bought these boots for walking in the mountains of Afghanistan, and they've performed amazingly.  I have had several other pairs of boots for this purpose, but these have performed the best by far.  The soles and sides have held up incredibly well to the rocks, and its been good to have waterproof boots.  On the downside, the waterproofing works both ways (who'd have guessed?) and the soles, while rugged, do not bend the way I like my boots to.  This puts extra pressure on my ankles and can make traversing uneven surfaces more difficult.  These are personal preferences, of course, so I don't dock the score for something that others are unlikely to have issue with.  They've held up great, but I might suggest you try them on before you buy them, or err on the side of getting a 1/2 size larger.  They seem a bit small for the size I bought.
