With some nuts and bolts and a leather punch tool, you are good to go!
P.S. For this instructable, I spray painted the nuts and bolt gold.
Step 1: The Shoe
Step 2: Measure and Mark
Here, I cut a piece of canopy repair tape (or any thick-ish flexible material) to the size of the flap on the shoe to use as a template.
Step 4: Mix and Match
Fierce shoes ready to kick ass! (Oh, I did spray paint the soles gold as well, just to tie everything in.)
So there you have it! Nuts and bolts instead of studs and spikes. Spray paint them with whatever finish you prefer, stud them on anything you want. Have fun!
