I've heard that the shoes basically die after racing one marathon. Is this true? Because of this, I haven't worn them yet, and saving them for race-day... however I would like to do at least 1 semi-hard long run (20-22 miles ~7 minute pace on crushed limestone) in them before racing in them. Does anyone have thoughts/experience with the shoe's performance dropping off after a few runs?
If it makes a difference, I'm 5'2 and weigh about 118 lbs
