I agree. It would be easier. You can't compare your experiences of buying other brand footwear to what these would be. We would be making these ourselves and know what the inner last sizes out to, all one needs to do is reliably measure their foot on a Brannock. If you have troubles buying footwear online with other brands of shoes (and I do too) - it's because the people who are selling them to you don't really know anything about sizing or the product. You can call Tres Bien Shop and say 'hey I'm a 41 in Common Projects... what size Margielas should I get?' and they will know because they probably own both niche pairs of shoes, but if you're talking about hassles with bigger stores and more unique or disparate products, it's because the people just don't really know and are guessing, mostly. Apples to oranges. If I make the shoes, I know what they measure out to. I will buy a Brannock device and gauge each of the lasts, it's as simple as that.
