The Athletics Spikes Needle 5mm are short, sharp replacement spikes designed for sprinters competing on modern synthetic tracks. The needle shape penetrates the track surface cleanly for maximum energy transfer and explosive push-off, while the 5mm length keeps ground contact minimal for lightning-fast strides. Ideal for 100m, 200m, and 400m sprinters who need every advantage on the track. Always confirm your track's spike regulations before competing to ensure the needle type and length are permitted.
