I've been getting some foot pain after walking long distances and I'm wondering if anyone can recommend any particular insoles that might help out. My heels start to get tender and my arches feel like they're stretched. Cheapo boots don't help I know but money is tight sadly.
Unfortunately with nothing else to go on I don't know what you call cheapo boots. I've bought boots from Alt-Berg for many years and they aren't what I'd call expensive for decent boots. However the service you get from them is outstanding. They'll tailor a pair of boots for you for not much more money than off the shelf boots in some other places. My police boots (Alt-Berg told me that they made that style for the police, I'm not in the force) have some heavy duty insoles which they fitted for me at my request, and although they're not exactly lightweight boots I can hike twenty or thirty miles in them at no notice and my feet are ready to go straight back out again at the end of it. The soles are very tough but I've had them a few years and they're now starting to show signs of stress. The uppers are still OK so Alt-Berg will refurbish them for relatively little money, and then I'll effectively have a new pair of boots.
There are so many things to go wrong with feet, legs, lower back etc. I really don't think it makes sense to pinch pennies on footwear. I can understand if you don't want to wear something like trainers when you're hiking, I feel the same. After several nasty ankle sprains in my youth I've become accustomed to the support you get from ankle boots, and for serious walking, especially over rough terrain, I'll wear nothing else.
Have you tried just an extra pair of thick socks? When I wear boots I always wear two pairs of socks, a thin one and a thick one. I carry spares so I can change them too, to air them out. It makes a huge difference to me, but I suppose I do sweat quite a bit.
