I bought a pair of the Kate urban with the leather sole from Valverde Botas. They arrived and not only are they uncomfortable they're massive on me! Now I have the pleasure of paying £18 to return them. 
I love these

Are they worth it? Comfortable? will last years? I'm sick of having cold feet and aching legs in winter from boots with no insulation or comfortable soles. I live in my boots right up until summer.
Any thoughts?
