1. You've asked why it's dyed both side. I've told you it's most likely drum dyed.
2. You don't seem to have much experience with higher quality shoes and are extrapolating your [mass production] shoes experiences to interpret your expectation for higher quality shoes. Your experience with 30-50 years old [mass produced] [military surplus] combat boots simply does not apply to shooting boots made by high end RTW makers or bespoke.
2. Invalid point. I don't use just combat boots as an example. I only used them for examples regarding how ugly the chrome blue would look as the surface is worn through and discoloration occurs. I don't extrapolating my experience of one subject and interpret it on the other one. I almost bought shoes from Carmina and many others, until it winds me disappointed of what materials they were using or what construction method they underwent even for the amount of money charged. It all comes down to a point where I concluded to myself that I'd rather save up some times to gasp for air and then go straight to a bespoke shoemaker, which saves me times, efforts, and even decisions. Like I said, it isn't like I always have time to go around, collect pictures and quotes to satisfy you.
