Recently been seeing lots of these in the shops. In particular this sort of thing in Russell and Bromley. Those are £400 - so I won't be getting them, but lots of shops seem to be doing cheaper versions. I need a new pair of knee boots (old ones falling apart) so I am very tempted.
A little concerned about the "Over Knee = Pretty Woman" aspect but think I can get away with it. They'll either be flat or with a small block heel. Intending to wear them with opaques or woolly tights and tweed/wool short skirts or shorts.
