Bought a pair of Dragonfly's for our short indoor and outdoor seasons (college) but I guess I'm racing cross country this weekend as well and don't have any xc spikes, and our team's spikes have not arrived yet. Can I still use them for xc, or should I find an old pair of xc spikes and just use those? I'm also worried about damaging them, as they weren't cheap. Any insight is appreciated!
