Can I return my (slightly worn) boots?

[roary]

Tried on a gorgeous but very expensive pair of boots. Very comfy in shop. Wore them to work today and have blisters not only all over my heels but UP MY CALVES. I wore them for quite a while in the shop but frankly this is the sort of thing that you would only notice if you wore them for a bit.

THey look fine, if I wipe the soles you can only JUST tell they've been worn outside. They will be a very expensive mistake if I can't return them....what should I do?

It's the Lytton riding boot in black patent.

I think the fancy design of the hobbs page thwarts a direct link, but bottom LH corner.

Success! Return with no problem, full refund! Now just to find the replacement boots!
