I've been covering these for a while:
www.asos.com/jeffrey-campbell/jeffrey-campbell-gauntlet-stud-point-heeled-ankle-boots/prd/6785060?iid=6785060&istCompanyId=6f061ed0-7427-4b6c-bb90-987c0bd08468&istItemId=xtiawirprr&istBid=t
finally went for it yesterday as they are on sale + 20% BF discount.
I think they are going to be crippling, but I just had to try them on! 
They remind me of Madonna's boots in Desperately Seeking Susan (which I have always lusted after)
