isnīt that the same model as these- while mine have a kind of *normal* steel heel?
If yes, then Iīd say they are walkable cuz very stable due to the wooden platform. but of course worst to your ankles and feet. and the question might be how elegantly it looks.
if not- I do not know.
as to optics for me it would be also about the form without a heel that I think them quite ugly.
ok, these mine are quite ugly too
... but very fascinating, I have to admit.
