Unfortunately, to our knowledge, there's no single 100% cruelty-free vegan climbing brand as of 2023. Notably, all the climbing shoes of American brand So iLL are vegan, but one of their lifestyle model is not. Also, some companies like Evolv (US), Tenaya (Spain), Ocun (Czech Republic), and Mad Rock (US) mainly propose vegan climbing shoes but do also have a few options that use leather.
