I have a pair of newish nubuck ankle boots with feel perfectly comfortable for a short walk, but every time I wear them for a long walk they rub somewhere (heels or toes or both). I tried putting plasters on the areas where they might rub and just keeping on wearing them, that's fine until the first time I don't use the plasters and then if it's a long walk they eventually become uncomfortable again. I can't quite work out whether they are just ever so slightly small all over (in which case why isn't it obvious as soon as I put them on?) or the texture is just a bit hard.
I read a tip about stretching shoes by wearing them with wet socks - I've tried that indoors, but would imagine it needs to be done for quite a long time to make a real difference. What else might work? I can't take them back now as I've persevered with them a bit too long for that, and I don't really want to sell them as they'll do for occasions where I don't have to walk much, if nothing else.
