I made two pairs of boots built on canvas deck shoes. I built up the soles with thick shoe crepe, and armored them in leather. The corrugated knee covers are leather, as well as the flexible boot horns. I have found that a more reasonable way to get good boots is to start with decent riding boots and add on the Klingon embellishments. Since I am not a cobbler,it makes sense to get good fitting footwear, then add the necessary Klingon accoutrements. It's also more cost effective.. I have both kinds pictured. Can you tell which is which?'
