My question is are new spikes, Nike Zoom Matumbo, before a bigger race good or is it to risky. The reason I pose this question is because, my old spikes ( Nike Zoom Matumbos) ripped, I used them for like 10 miles.I also for instance run basically the 1600m, and 3200m, if that means anything to others. No, I do not like the Nike Victorys. Anyways, the reason was some idiot put stuff on it. Would it be a wise idea to use Brand New Nike Zoom Matumbos at the state meet. Is that basically what the pros do? What do is the idea on this?
