Do any of the vets know if Razor siping has to be done by a specialized supplier or can any factory do it? What exactly is the process? I am thinking it’s something like the cutting dies with a razor sharp edge pressed down onto the finished bottom plate?? Any help is much appreciated!
You’ve pretty much got it as far as I know. It’s a special kind of cutting die with the thin razor edges and is done as a post molding process. I would think that any outsole supplier should be able to do it, but when in doubt, ask. I’ve only used it in a few shoes, but have never encountered an issues with specifying this type of treatment.
Mr Kuchinsky, you are the MAN! Thank you sir. I’ll see what the factory can do =)
