In my experience. Soft calf, next to suede, will experience the most profound stretch. However, if your smaller toes are visibly protruding you'll never fit into the shoes comfortably and should try to return/move them. Sizing up a width may rectify the problem within the toe-box area but may create issues from the forefoot to heel. I've been able to simply size up by a half all together and it's made all the difference.
I was in this boat and when I spoke with Patrik from Skoaktiebolaget he was able to add a fitment piece in the toe box. My instep is super low and so going up in width would cause my foot to slide around the shoe so without affecting that too much he suggested adding a few CMs on both toe boxes. I took his advice on my sinatras and I just tried them on a few times and they instantly are feeling way better. It did have its upcharge but totally worth it in my opinion
