Hi! I’m looking to buy track spike pins. I want to replace the set of track spike pins that come with Nike Dragonflies. They are somehow sharper and more resistant to corrosion(Rust during steeple and rainy days) than those random spike pins I bought in the past.
I know the pins are 7mm pyramids. But unsure what kind of metal to get. There are spike pins made of steel, carbon steel, alloy steel….
Hopefully someone can give me direction on which to buy. Thank!!!! :)
