In reply to Fellfaller:
I think that footwear is about the most important of all our outdoor gear, so it is not an area to penny pinch. If you are really getting back into this seriously, you are best with two pairs of boots - one well-made set of proper hill walking boots that can cope with rain, mud, scree, some snow, and another pair of lightweight hill "shoes" for dry conditions. For the latter, I prefer climbers' descent-type shoes with a thin vibram sole and thin leather uppers. I am not a fan of lightweight trainers, with breathable tops, that let the rain straight in! Last summer, which was unusually dry in the UK, I used my descent shoes almost the whole time; now I am back to the hill-walking boots to cope with mud etc.
