If you find a skilled leather worker that makes quality saddles and such. Pair them with a shoe maker which are increasingly hard to find anymore. Take the time to explain in detail what you are wanting. If they are willing to work together and take the time they can bed a pair of climbing spurs into heavy boot soles and build a heavy leather boot around them that keeps them stable with a steel shank to distribute the load under the foot, and the pressure on the calf/inside of your shin will be spread over a larger area and shielded by several layers of leather. They are stiff as hell till they are broken in, and hot unless you are in a cold climate. It can be done but no company mass produces them that I have been able to find. I had a pair made back in the early 90s. They lasted for 3 maybe 4 years before they started coming apart. I looked for the men that had made them for me. One had moved out of state and did not want to put the time into such a crafting again. The other had retired or something. I could not find him. I have not been able to find 2 capable craftsmen that were willing to work together to make more (That I could trust for quality), and I would not even want to know what they would charge these days for the work put into it.
I admit that even back then over 300 dollars was I think a good price to not hurt at the end of the day. Depending on how well they are made as to whether they are worth it or not. Good luck finding those unicorns. If you ever do let the rest of us know... I would make a drive to get a pair fitted if the price was not to shocking.
