ISO Boot Brands that run small

Looking to buy my first pair of new boots (I’ve bought used boots before, but kinda want a pair that only my feet have been in). I’ve been having trouble finding a pair that fits me. I wear a US mens size 6-6.5 usually, and have narrow feet. Seems to be just too small of a size for what I’ve seen online. I’ve tried Ariat’s size 7s after reading some reviews of them running smaller, but even they were too big. Wondering if there are any other brands out there that run small that I could try before looking in the kids section.
