I’ve had these for abt a week and I feel so bouncy and light. I dropped my time by abt .1-.2 in the 100. But don’t get them if your just getting into track.

very poor quality falls apart very fast lace cap fell off hole in my spike and more developing on the other, stains socks pink when slightly wet and when dry lightly stains. These spikes work great but arent worth the money hopefully i just recieved a faulty pair. had since indoor and worn 25ish times. im a sprinter so i dont use them that much even.
