Bought winter boots from them. So not sure on what size to get, because you should buy those larger. I also have wide feet too but they only offer them in M not E or wider. I don't know the brand yet, so no knowledge on how they fit vs size listed. Finally ordered after research online.

Instead of the size I ordered, a 10 M, I get a 10 AA. It doesn't fit obviously as it's too narrow. Contact support and ask them what to do. They assure me I should get them exchanged and they will add a note to the warehouse to make extra sure I get the 10 M and not accidentally a 10 AA again. Days later I get 10 AAs again... Same chat with support who probably laugh to themselves at the stupid customer 'note to the warehouse haha' (do they actually do this? Would any overworked/underpaid warehouse worker even look at that?). I have to cancel the order and order a new pair in 11 M, which if I actually get that means they're gonna be too large. Luckily an 11 AA arrived. Go figure.
