I picked these up from Yoox and wondering who the maker might be. They were made for Gruppo Clark. There are numbers along the inside of the heel, but no other identifiers other than on the soles, pics below.
Just to further muddy the waters here: below is a pic of the box from a pair of boots I bought from Yoox. At one point it had clearly been on Farfetch, I don't know what the price was on FF, but the Yoox price was very good.
I've never found the pricing on Farfetch all that enticing compared to Yoox, and they rarely have anything I want in my size
They started doing that because some Drumohr items were made in Scotland and had English sizing and some were made in Italy with Italian sizing, so e.g. a size 50 could either fit really well or be enormous. Most of the Scottish stuff is long gone, but for awhile it provided a great opportunity as those sweaters got marked down to ridiculous levels, almost certainly due to confusion over sizing.
