The product choice and delivery via Bergzeit is good. I sought vegan climbing shoes. Information directly from Tenaya states "The only model that is not vegan is the IATI that combines natural leather and synthetics." (June 2022) However, using the Bergzeit websearch for vegan climbing shoes, it does not propose Tenaya RA, which I bought based on manufacturer info. So perhaps a review of the vegan category would be useful - maybe a separate filter ?!
