To be honest Iain, I've only walked about 50 miles in these boots but I must say that early indications are that they are great. That said, when I walk on the moors, I wear a pair of Berghaus Yeti gaiters which allow me to wade through rivers almost up to my knees and won't let any water in. I have found them to be supremely comfortable to walk in, so light that you feel like you are skipping up the hills and no blisters to report. However, I have managed to bruise the big toe on my right foot where it was bumping against the end of the boot on descents. I think this is where I didn't have the boot laced tightly enough under my gaiter and was too lazy to stop and sort it out. Not only that but I still have black toe nail on my little toe on the same foot which I got when wearing my Meindl Borneos so I think it's too early to blame the boot for my bruised toe.
Now, I know that for a lot of people £100+ is a great deal of money to pay for a pair of boots and I wouldn't recommend anyone buys a pair of boots without trying them on first unless they know precisely what size they need. Of course, you will only know what size you require by trying the boot on. Maybe, if I was buying a second pair of these, I would look for the replacements on line in the same size.
The other thing to bear in mind is that, unless you are planning on walking long distances, expensive boots are just not necessary. If you only intend walking a couple of miles max to your intended location, then I would suggest a good old pair of wellies for autumn, winter and spring use. These are waterproof and allow you to wear several pairs of warm socks to keep your inactive feet warm. In summer, why not wear a pair of leather 'army' type boots or even a pair of Karrimore type trainers or cheap walking boots? Both can be had for about £20 for the pair. I wore my German Para boots when we went out this Sunday which were perfect for what we were doing (which wasn't a lot).
Anyway, to cut this overly long story short, I really like the Salomons. I haven't had them long enough to give them a really good appraisal but I will be wearing them to climb Slieve Donard, Ben Nevis, Scafell Pike and Mount Snowdon at the end of May, so I can give you a proper report then.
Hope this helps
