I hesitate to pour cold water on a brave venture, but I fail to see the appeal of the shoe styles so far shown by Cross Sword. The uppers are conventional (distinctly boring) men's styling which I for one would not wear, regardless of the heel type. And the heel (with a gimmicky insert) is rather too feminine. The price is going to put these out of reach for anyone but a fashionista too. Sorry!
If CS (or someone else) introduced some more neutral loafers or ankle boots with a tapered toe and a plain cuban or stacked heel of (say) 3.5" for £100 or so in sizes above UK8, I guess there would be a fair interest. Until then, most UK male heel-wearers will buy women's styles (if they fit), have something custom-made (which need not be expensive) or go without.
