These are great, I recommend them whole-heartedly.  I bought them in the white patent as a Christmas present to myself.  Very nice with a red skirt and tights.  The shaft is really high, they come up to the top of my thigh, and that's good.  They feel comfortable, although I suspect they may be a little warm in the summer.  Great heel height, very easy to walk in.  Buy one half to one full size larger.
