Okay bro, it's simple, just get spurs...
Haha just kidding, But, in order to have that sound, be creative man. I have multiple suggestions.
One is to get a metal rod or thin sheet rod. I call it a sheet rod as stupid as that sounds because its those long lengths of steel that are flat, not a rod.
Anyways get metal is your objective here and think creatively, use your head in terms of physics. What thickness of metal, length and other factors are going to affect the sound of the clinking, how many individual pieces of metal should be on one rope or band around your leg? What should be your arrangement of the metals to make the proper clinking sound? Use your beautiful and unique head and imagine what it will all be like. You know physics just play with it!
ALTHOUGH that is extremely unsafe and I do not reccomend someone walk into a convention center with a bunch of metal rods hanging down at your ankles. Now use your same imagination and imagine if there was an emergency and you tripped and fell onto the metal..
So yeah that should ever be done unless it's contained in a metal container which is just silly.
One other suggestion is, using metal again, get washers or something that will make noise, metals such as steel make good noise, alluminum is soft and wont get any clink sound.
Anyways have small rods on a system that simply wraps around your legs with the washers all on the rods. So each time you walk, from the gravity the washers will come up and clink down. Although that would take almost possibly stomping! Give me a few hours and I'll come up with more ideas!
Another way is to program a motion sensitive speaker so that everytime you hit the floor at a good normal pace it will play a HQ spur sound. That you can recreate with use of metal objects and tools just as the sound effects people did for stuff like that. Now of course they could have just gotten a spur and used its sound which is what I think they did but get creative with it and be safe! Those first examples are just to expand your horizon to physics because having metal rods dangling around your angles is EXTREMELY DANGEROUS. You do not want metal rods sticking out of your leg...
