So I've been using the Nike Matumbo spikes for a little while now, and I have to say, they really do the job. I've also worn the cheap Nike Rival LDs (which sucked)and the Saucony Kilkenny flats(which feel like light shoes with no cushion, not "fast" feeling). Admittedly, I've also raced in Vibrams. Not a fun feeling on a track. The Matumbos just blow everything out of the water, and, to my surprise, work very well in XC courses as well as the track.
Are there any better spikes out there?
