^ Well,... in this particular case, the length is important. If you follow this thread, you may have noticed that I'm not new to NDC footwear. I own three pairs, to be exact. My newest pair is a chestnut brown cordovan dress shoe that I bought at their flagship-store in Belgium two days ago. I bought them in my usual NDC size, which is 44 and true for the "Rico"- and "Sunday" shoe. When I arrived back home and tried them on again with a thinner pair of socks and walked around, I realized that they fit significantly bigger than the "Rico"- and "Sunday" shoe and that there's almost too much wiggle room in the toe area, though. I could definitely size down on them. They're not as narrow as my other NDC's and were made on a completely different last, which is based on a Pre-World War 2 last. Consequently, I called them today and asked them if there's still a pair in 43.5 or even 43 available. Result: One last pair in size 43.5 ! I also asked them if they could roughly tell me how big the length-difference between a 43.5 and 44 is. Unfortunately, I got the last pair in 44, so they didn't have the change to measure both sizes and tell me the exact length-difference. All they could say is that the difference between half- and full sizes is usually about 0.5cm ( +/-1cm, depening on model ), which isn't quite much. And now I wonder if it would be worthwhile to take the "hassle" and drive back to Belgium and exchange them for the pair in 43.5, or if ~ 0.5cm is so minimal that I should just keep the pair in 44 and get a new insole. Aaarghhh...
