What you'll need:
2) spikes (I used spikes with screw inside),
3) awl to make holes,
4) white pen to mark, where to make holes,
5) small screwdriver (I borrowed one from my boyfriend's kit).
Step 1: Mark, Where the Spikes Will Be
Step 2: Making Holes
Step 3: Putting the Spikes In
So take the bottom part of the spike and put it through the hole. Then put on the upper part of the spike (which is the spike itself) and screw them tightly together. This is where I used the small screwdriver - I used it from the inside of the boot. Well, it wasn't easy, but it was worth it.
Step 4: And It's Done!
Thanks for reading and enjoy wearing them!
