Size 13 Cone Spikes
I purchased my awl and spikes from Studs & Spikes. They have a million and one different studs and spikes to choose from, and the quality is fantastic.
The backpack is by Everest and I purchased it on Amazon. This particular model comes in a ton of different colors and seems pretty durable. I love the idea of a baby pink bag with gold studs.
Now I want to spike everything.
