This is a riff on Nubby Twiglet's spike shoes from a couple months ago. I decided to use some cheaper canvas shoes (these are from Forever 21, and there are some good ones at Target, too), and focus the spikes in the back.
These spikes were purchased here - your friendly neighborhood goth superstore, and they come with prongs or screw-in backs to secure them to your material. Easy peasy.
The End.
