Hi all, long time reader but rarely post!
I'm sorry, but I'm posting here for traffic, as I know Mumsnet will have the answer!!
I've just worn my lovely new Christmas pressie Carvela Chelsea boots....
I wore them with slightly thicker socks at first, but had to quickly change them as they made them tight and really pinch my toes. (They were not overly thick, FWIW, I think I've just got dodgy feet!)
So then I changed to a thinner pair, and all was well, or so I thought!
As I'm walking around, outside, my socks start slipping down into the boot so that the leather top of the boot is then rubbing like crazy on my leg! 
So, is it my feet, is it the boots, or is it I need a special type of socks?!
I can't return them now I've worn them outside, and wouldn't want to look ungrateful to the friend who bought them for me! I want to wear them, they're lovely!
Please help! I promise I'm not normally such a rubbish adult!
