I had no idea Kamina wore sandals the whole time until i had to look it up. In many scenes, both the footwear and the lower portion of the cape are outside the frame.
Whilst i have at least some practice with hands, i haven't made any barefooted figurines, so the probability of messing up the toes was about 99%. Might have been doable, but it sorta came out of nowhere so i went with boots.
Besides, it is rather odd that someone who has lived most of his life around and beneath rocks and stone doesn't wear appropriate shoes .
I guess stubbing toes passes for a hobby for him .
