The ubiquitous Demonia Stack, king of platform boots!
Trained with images of the "201" variant: matte black PU leather and ankle/low-calf height.

Weight 0.8 - 1.0

(st4ck shoes:1.2)I tried to include plenty of training images with the boots in a horizontal orientation, to assist with lying/on-knees positions.
