For regular climbers who get outside or to the climbing gym at least a couple of times a month, you'll wear the soles of your climbing shoes down fairly quickly. Or it may be more accurate to say you'll wear them out in one tiny spot that must be repaired before they become too damaged to be fixed. Considering the cost of a resole is $30-50, compared to $140-200 for the average climbing shoe purchase, my friends all resole their shoes at least once or twice before trashing them.
