Rock climbing shoes are designed to provide a tight and precise fit, as well as unparalleled grip and friction on the rock surface. They are also made with soft rubber soles that easily conform to irregularities in the rock, providing even more grip. Because of these features, it is important that you take good care of your climbing shoes in order to maximize their lifespan. If you're a frequent boulderer, you probably need to buy new climbing shoes every other year. If you a frequent outdoor rock climber, you will probably need one pair of new climbing shoes per year.
