Just picked up these track spikes that I'm going to try and use as a racing flat.
This guy has a local cobbler put new soles on track spikes with some good luck. But, I'm hoping I dont need to do that because the full sole on these look to be rubber and the spike holes seem to be sunk deep enough down.
For $22 shipped, not a bad price to try this out. Also, the heel appears to be narrow enough to fit easily into the footbeds of my Huki.
