Adizero Avanti / ADIZERO AVANTI 25.5cm Listed as "Like New," but I haven't worn them since trying them on, so they're practically new! The cushioning is incredible, making these spikes suitable for all middle and long distances! And, they come with brand new needle pins! Of course, there's also the special wrench for changing the pins! Wearing parallel pins increases grip and speed! Wearing needle pins allows for smoother foot release, reduces fatigue buildup, and improves speed endurance (maintenance)! If you're interested, please consider them!
