Absolutely I agree with this. 10" really only comes into play out in the woods to avoid twisting your ankle and extra support. I have never really found a difference between it and the 8". It still is comfortable, just a longer break in ever so slightly.The difference between 8 or 10 isn't that much. if I had to choose, I would choose the ready to ship.
On a curious note I am currently on the Stitchdown Discord. They are praising 7" like it is some ideal height. I'm not sure why or if it is a flexibility thing? From what I can currently ascertain it has more to do with a 7" boot being able to fully patina, give the flexibility of 6" boot, but the ankle support of a 8".
I can't comment myself because all the boots I have owned have been Chukkas, 6" boots, 8"(my favorite), or 10" in terms of height. I'd be curious to hear viewpoints or experiences of people on here though. Is 7" really a magic number? Or is it something more suited for casual use by fashion moguls?
