Bought these 4 months ago as a birthday present for my wife but they are too small. Her birthday was last week, so beyond the time limit during which they can be returned. :-|

They are size S/M, which according to Endura, fit men’s 5-6 or women’s 37-39.

Cost £25 + postage new (on sale) – would like to get £17.50 posted if possible pls.
