I posted a picture with my last post, it must not have come through. To get the spikes out, I soaked them in water for a few minutes, up to the height of the soles. I worked them back and forth a few times, then they popped right out.
Hopefully, the picture will post this time. Hope it helps you guys find the spikes you need. By the way, the standard color cyclones will work too. I checked both sets at the store to make sure they're the same. The standard cyclones are brown and black though.
