The lifespan of climbing shoes varies depending on various factors such as frequency of use, climbing style, and personal preference. On average, a pair of climbing shoes can last anywhere from 6 months to 2 years. If you climb regularly, say a few times a week, you might expect them to last around 6 to 12 months. However, if you climb less frequently or take good care of your shoes, they may last closer to the 1 to 2-year range. It's important to monitor the condition of your shoes and replace them when the rubber sole wears down significantly or when they become uncomfortable or ineffective for climbing.
