Used about 7-8 times on artificial turf. About 90% of the studs remain, so there's no problem with use. If you purchase, I will clean the main body, laces, etc., as much as possible. I will also negotiate the price as much as possible. Thank you. Below is the official adidas description. Lightweight, fit, and insane rebound. Everything for a moment of speed. The X Crazyfast was developed to bring threatening agility to your feet. Show off your threatening agility on any pitch, whether it's a ground or a futsal court. - Model Name: CRAZYFAST - Color: White - Brand: NIKE - Sole Type: Spikes
