Recently both my track spikes and xc spikes wore out. I need to buy new track spikes, but I think it would be best to only race in them to make sure they last as long as possible. What would be a good spike to train in for track workouts? I was thinking along the lines of an xc spike but I wasn't sure. I need something durable and not too expensive since it will wear out fast because I'll be running in it a lot. FYI I'm hoping to run around 2:05 and 4:40 this year, and I am 6'3'' and 165lb (Not sure if this matters but I figured I'd throw it out there). Any input is appreciated.
