In reply to peter.herd:
I'll second the scarpa rockettes, they're great, (although they take a while to break in properly and might be rare now.) The scarpa instincts also come in a lace version for tuning the fit.
It's worth looking at sportiva's miura lace too. The men's miura is a fairly slim fit, (i'm assuming the women's version is slimmer but you can't get that in the uk.)
