Set of 4 spike pins with a dedicated installation tool. - Quantity: 4 spikes - Accessories: Installation tool included These are dedicated spikes for Giro dirt shoes. The soles of my Giro shoes were ruined after one race, so I'm selling these because I'm changing shoes. There are scratches and some rust. After removing the spike bodies from the shoes, they were cleaned and soaked in Wako's Rust Penetrant for 24 hours for rust prevention. ● Other notes: Please refrain from purchasing if you are overly concerned about minor details.
