I think don't think skinny calves look nice on men or women, or skinny thighs either. Shapely legs for women and football legs for men.
I did have trouble finding three quarter length boots that weren't too tight, a few years ago, but as I've aged, the upper calf is the same measurement but the lower part seems to have disappeared and have no more trouble. But my lower legs from ankle upwards are far too long and shapeless now, so I am not pleased grrrrrrr. Rather have them as they were.
