They are from a german clothing company called "Tom Tailor" and I bought them on Amazon DE were they were just called: "TOM TAILOR Women's 8091002 trainers"

I searched for "Tom Tailor 8091002" which is the item model number according to the product details, but you get just more amazon results. The results do include Amazon US, Amazon SE and Amazon UK though in addition to Amazon DE.

On all of them the stock seems to be low and the sizes are mostly sold out. I was lucky getting the last pair of size 43 EU from Amazon DE.

I couldn't find anything on the tom tailor website so it's probably an older product they don't make anymore.
