Comments: These are amazing! I haven't used them in a race over a mile yet, but so far I love them. The stiffness of the carbon fiber doesn't bother me at all.

Comments: The spike are the best I've used, had matumbo last season and these spikes feel so much faster. The flywire keeps my foot held in position even on the indoor track, the carbon fiber keeps you up on your toes through the 800 and doesn't feel uncomfortable at all. By far the best spike out there, would recommend it to anybody that runs right up on thier toes.

Comments: These spikes are amazing. Definitely worth the price, and a substantial upgrade from the previous model. The carbon plate is great, although running on it takes some getting used to. I recommend sizing half size down since they run a bit big.

Comments: I just got a pair of these and I thought that they were much too stiff for a 2 mile to 5 k shoe, but I did like them for the 800 and the mile. The forefoot really started to bug my foot if I wore the shoe for too long.
