Just tried on the Neumora. Apparently these initially had defects with the straps and were recalled. In store stock was very limited. This shoe is on the 333 last. I normally fit a 10D in most AE lasts, with some better than others, but all mostly consistent in length. I was swimming in these in a 10D and even a 9.5D had enough space for me to slip my thumb in behind my heel. I would guess this is in part the semi slip on nature of the design, but I think it is mostly the size of the toebox which is quite long and wide. If you decide to buy you definitely need to try on first. I passed on these as I did not like the look of the squared off toe. Otherwise the design is fine, with a very unobtrusive welt, and a deep brown leather. I now just need to hear back from my email to Meermin as these seem to be what I am looking for.
