I'm going to continue soaking up free advice until you guys start charging me.
I've finally given up on Meermin due to their low QC and painful break-ins. I ordered a Carmina Rain in 8.5UK, and an Inca model in both 8.5UK and 9UK.
Both the 8.5 models were too tight width wise and also in the instep. The Inca 9 fits pretty well, except the instep has a pretty steep V.
The rest of the shoe fits well, there's no way I could go up in size due to the length. For reference, I've been measured at Brooks Brothers as a 9.5E US, but it seems like I might be able to make a 10US/9UK work on occasion.
What do you think, gentleman? Do I send these back? And does anyone have recommendations for my wide and high instep foot? Some have recommended Bonafe to me, but I emailed Skoaktiebolaget and they didn't seem to think there was a huge difference between the wider Carmina lasts and Bonafe.
I'm about a week behind so I'm not sure if anyone answered this but I think Bonafe (at least the 946 last) has a slightly higher instep than Carmina Rain. Not a perfect comparison pic but you can see that the V is slightly wider in the Carmina on the right than the Bonafe. I hope that helps. They're both 7 UK btw.
