FAQ

What´s the material?

The Cores are made with ferrocerium, which creates even more sparks than titanium. They’re encased in high-performance 3D-printed housings.

How fast do I need to go for them to work?

Our cores spark even if you just brush your foot over the ground. Faster speeds = more sparks!

How long do they last?

It depends on the road, pressure, and speed. Like a bag of chips, it varies. Could be 5 minutes or a week!

Which ones make the biggest sparks?

Both Obsidian and Stealth make big sparks. Stealth is easier to walk in but Obsidian lasts longer.

How are they attached?

Simply use the included super glue and adhesive pad. Fits almost any shoe!
