Knee high Volatile Chellin boots, GREAT for tiny calves!!

I have approximately 12” calves and it’s nearly impossible to find boots that fit my legs. I bought these from Zappos, and they’re pretty much perfect! They have a zipper on the inside, and an adjustable lace up the outside of the uppers. Based on my measurements in the pictures, it looks like the shaft from heal to top of the boot is approximately 16 1/2 inches tall. The calf measures approximately 5 inches across at its tightest, and can be loosened for wider legs. The heel is about 1 inch. They are in excellent condition. I have only worn them a handful of times.
