Thank you so much ladies! I wore them whole day (6 h of running around, 6 of sitting in front of the computer) and my feet were mostly happy. And nobody in the lab made a snide comment, meaning they fit in.
But, I have to admit that I am somewhat disappointed with the comfort level: it is good but not great. The heel itself is fine, it is the sole - not soft and padded, feels pretty hard, more like that of shoes than sneakers. It could definitely be improved by insoles, but they run a bit small and are already fairly snug so no place for them. They only come in whole sizes, not half ones. I mostly wear 8, rarely 8.5, so i went with 8 in these. I wish I bought 9 and had space for insoles, but I did not realize how snug they will be. I tried them briefly on last night and they felt great, different story after lots of walking. I can not exchange them now after I have worn them the whole day. At the moment they are about 6 h shoes, and if the leather stretches with wear (which I really hope it would) then I might have space for foot petals which would probably move them into 8 h category. Sigh...
