You are comparing a brand who make one/two pair of shoes from an hide, with a brand which use even the last millimeter of those expensive leather.
Obviusly JL select the denser and better part of the hide for his vamps, with Meermin is only a matter of luck, some pair can be perfect, others very poor.
Anyway the creases on your Meermin are perfectly acceptable.
Thanks, I am sure is not only the leather (this leather is not bad at all, but of course in not JL). . And yes, I do not care too much as far the fit is good.
All manner of considerations enter into this--the length of the caps; depth of the forepart of the last; width of the insole; the quality and substance of the vamp / upper leather; the quality and thickness of the lining leather; the underlying structure... such as whether there are mid-liners or not...the structure and articulation of your feet.
Foot to foot...nevermind the shoes themselves... even if your feet are exactly the same length, there can be discrepancies in the way the shoes crease. And if one foot is even slightly longer than the other (and almost every one has such feet) it is almost a guarantee that the shoes will crease differently.
I suspect the business with feet is self evident but combined with the aspects of the shoes that are different and the best one can usually hope for is "similar."
Thanks, I think the depth of the forepart (first think I thought about) and the lenght/width of the toe cap play a great roll together with the quality of the leather.
