I'm looking for a pair of genuine leather, round-toed, low-heeled but thicker-soled Mary Janes, preferably flexible in some way and good for extensive walking. I've seen quite a few ones second hand, but I'd like to try before buying and/or have the possibility of returning.

I've scouted the typical shoe stores that used to make these but found nothing similar, just Mary Jane flats with thin soles and almond/narrow toes. Are there any brands doing this style nowadays besides Dr. Martens (too heavy and hard) or sportswear brands? Must ship to Europe, ideally located in the EU but not required.
