How well do Nike spikes work for Cross Country races?

I have these shoes ( http://www.nike.com/index.jhtml?l=nikest... ), and if I use metal spikes, these shoes can be used for XC. Do you think Nike spikes will be good for a 5K? How much faster do Spikes make you?

How well do Nike spikes work for Cross Country races?
spikes in general are amazing. i have these adorable pink nike spikes and they made me drop 40 seconds!
Reply:Spike help a lot in X-Country, but I don't think I would use that model. It has been a while but Nike makes X-Country spikes that are wide at the heel and have more padding and different patterns of the waffle. This is a Middle distance spike. It isn't really designed for off road use.
Reply:Like the person said ahead of me, I felt I lot faster because they were a lot lighter. I would make sure you are fitted into those though. Spikes are good for grassy areas, muddy areas, and they keep your running shoes in better shape. i definitely recommed them
Reply:Those look good, but each person is different. Spikes don't do much to make you faster, thats up to your legs. Spikes feel lighter on your feet which makes up a small part of you going faster and they give you a better grip on cross country terrain. Those nikes look good though, can't hurt to try.
Reply:I used Nike spikes during high school/college cross country. They seemed to help a lot (but I'm sure part of that was mental!) Running during practice with regular shoes, and then putting the lighter spikes on for the race made me feel a hundred times quicker! I would recommend the Nike spikes for a 5k.
