To use more technical terms, one of the boots has a very fine leather break (many wrinkles per inch), while the other boot has a coarse leather break(fewer, deeper, coarser wrinkles per inch)
Not sure if that implies one is split grain or not.
Any suggestions on what I should do? I didn't think it'd be a big deal, but I'm worried about my boots
I know this is an older post and the conversation has moved past it but info must be given!
You don't have a full and split grain boot. Both are full grain. What you are seeing on the inside there is a result of leather being taken from different parts of the hide; think of it like cuts of beef. The best quality leather comes from the shoulders and left and right single bends, lastly comes the belly. If you're sourcing for a premium first cut type of deal, you will pay more to get the best cuts (shoulders and bends), but if you're looking to keep costs down, you will go for backs which include one side bend, half a shoulder and one belly side.
The "weaker" areas (I presume the areas where there isn't as much muscle mass and are considered more vulnerable) tend to be softer and have a different nap on the bottom side. This is wear you get the fuzzys. A "split" is more commonly known as suede, and it's easy to distinguish between suede and leather with a top finish. Your boots would be obviously different on the outside (not the inside).
Those same weaker areas also will develop different types of wrinkling, it's still natural wrinkling, but it just looks different. We tend to prefer things symmetrical, but you shouldn't worry too much about the quality as full grain leather is pretty sturdy.
Hopefully that helps alleviate some concerns.
