Do new dragonfly spikes need breaking in? Would love to wear them for a 3000m tomorrow (season opener) but they haven't been used at all yet. Is that a terrible idea?
I have a year-old pair which I could wear instead, which I train in, but I'm gunning for a PB and targeting a minute barrier so I'm tempted to go with the new ones even though I haven't broken them in; I need that extra few %.
