how do i know if my climbing shoes are worn out?

There are a few signs that can indicate if your climbing shoes are worn out and need to be replaced:

1. Sole Wear: Check the rubber sole for significant wear. If you notice a smooth or shiny patch in the middle of the sole, or if the edges are worn down, it's a sign that the shoes have seen better days. A worn-out sole can affect your grip and performance on the rock.
2. Decreased Sensitivity: Over time, the sensitivity of climbing shoes can diminish. If you find it harder to feel the rock or accurately gauge your footholds, it might be a sign that the shoes have lost their sensitivity due to wear.
3. Toe Box Deformation: Examine the shape of the toe box. If the rubber is excessively stretched or the toe box has become misshapen, it can affect your ability to accurately place your toes on small holds.
4. Lining Damage: Inspect the lining of the shoes. If you see holes, tears, or excessive wear in the lining material, it can cause discomfort and reduce the overall lifespan of the shoes.
5. Odor and Hygiene: If you've tried various methods to eliminate odor and maintain hygiene but your shoes still emit a persistent and unpleasant smell, it could indicate a breakdown in the materials of the shoes, making them less effective and less pleasant to wear.
