I need a pair of spikes for cross, under 70 or 80 bucks, that work well. I get them through my school, so I have a discount, but the amount I mentioned is the limit. I'd rather get distance track spikes, but I'd be open to good cross spikes. Is there a place that lists all or most of the spikes in production today? Or can someone suggest a few good models to look at (and possibly order from runningwarehouse?)
