My father has very wide feet, this is for him; Until 2018 we bought this brand almost exclusively because they sell very large sizes, he would be comfortable with 13-14 2E Própet. Revain's sizing chart has since changed from what used to be 2E to something like XXW. I don't know what's the problem with Própet at the moment because they seem to be getting smaller every year, we've ordered about 4 other pairs in that time. , same problem with all, this new pair we ordered was 16XXXXW so we thought it was more than enough. He got running shoes (16 5E) and. literally just a few millimeters wider than what I would wear, which is your standard D (currently M). Don't buy Própet if your problem is wide feet, now their size is misleading and the quality is not comparable to other brands, they wear cheap and loose, but now the prices have gone up a lot and the quality has not.
