Got these boots a couple weeks ago from a shop in Greenwich. They are by Claudia Ghizzant and despite appearances are very comfortable. The platform gives me the same heel height as my brogues and the thick soft soles make them comfortable to walk in. I just bounce along. These are the first heels I have used on the Brompton in ages and have a good grip on the pedals.
I still haven’t found a pair long boots to replace my much loved but worn Office boots but I will continue on my search.
