The spikes I used to create this look are called Screw Back Spikes and come in various sizes, colors & shapes. There are many internet sources to purchase them and I have provided links in the first step. I definitely recommend shopping around for different price points. Ebay seems to have some of the cheapest screwbacks, but they typically ship from Hong Kong, which can take a couple weeks to arrive.
If you've never used a power drill before, it's really no big deal. I recommended using an old shoe for practice first, before you start drilling holes in the heels you will use for this project.
I was able to create these shoes for less than $40 total, including shipping costs. (I already had the shoes).
Step 1: Tools & Equipment
Step 2: Drill holes in the back of the heels
After you have drilled the holes, take the head of the screw and punch it through the inside of the heel, so that it sticks out the backside. Next, take your desired spike and screw it on until it is tight.
Once you have finished screwing in all of your spikes, take a screwdriver and screw the screws tightly on unit they are flush with the shoe.
Step 3: Drill holes into the side of the heel
Punch the head of the screw through the inside of the heel, into the back of the heel. Screw in the spikes.
After the spikes are screwed in, use a screwdriver to tighten the screws so that they are flush with the shoe. (I used a mini screwdriver). This way you won't feel the head of the screws when you walk in the heels.
Step 4: Glue heads onto back
Take a screw and place a dab of the super glue gel onto the head of the screw. Place the head onto the back of the heel in desired place and press and hold for 15-30 seconds or until secure. Repeat process until all of your screws are in place. Let the screws dry for 30 minutes. After 30 min, screw your spikes onto the back of the shoe.
I found that most of the screws went on with no problem, but I had to glue some of them on multiple times. If anybody knows of an industrial strength glue that is stronger then the gel, please let me know. I thought of using an EPOXY, but it would dry an amber color and might stain the shoe.
Also, I recommend keeping a bottle of acetone on hand. Working with such tiny screw and the super glue, you are bound to get some on your hands. It comes right off with just a little bit of acetone.
So far, none of the spikes have fallen off. I will post updates each time I wear them.
