If the narrow is too tight I would just go up a width.

Don't forget your feet will splay out more when you stand up and put your full weight on them. The more you weigh the more they splay usually.

I find that I also go down a half size in size with NB if I go up a width fitting so if you on the border of the next size down I would try to get both sizes and return the one that doesn't fit as well.

Europe it was twenty for the high end machines, it now matches the US, which is a huge down grade

Haven't they also dropped the lifetime warranty as well? That used to be the big selling point of them to me
