I ordered both Size 7.5 ad 8 in these boots-due to all the reviews;
as well as having experienced a pair of Jambu Kyoto shoes that were short in the toes.
The 7.5 fits generously on my foot. It could be that different materials run smaller, but I ordered the Congac leather. I would say they run true-to-size and maybe even a bit large.
A couple things that I definitely do not like and may cause me to return these (despite the fact that I have wanted these boots since they first came onto the market)
  The ankle portion does not close and sort of flops around; and I do not like the white stuff inside because I tromp through every sort of terrain..and it will soil.
I am actually considering puncturing the leather to enable me to lace the boots all the way up.
  Also, the material that the wedge is made simulates the look of wood....it is a faker;... suspect it will chip.
The rubber bumpers on the toe portion look sort of crazy-giving the shoe an asymmetrical look.
They are not bad-considering the price, but I still like my J-41 Pacific boots much better (both pair now 5 years and still tromping)
So-all in all: price point in mind; they are okay-but I would never agree to paying over $50.

Okay! I re-ordered a smaller size and due to the lacing system; I couldn't wear them without some discomfort. (The lacing is fairly intricate
However, I also reordered the Size 7.5. Guess what? The crazy asymmetrical look of the bumpers was not present in the second pair and they fit much better too!
I have just spent the better part of 2 hours placing new holes in the top flap and figuring out how to re-lace the boots. It works for me!
