Yes, but I would only recommend you use it on shoes that have caked-on polish from a person who didn't know how to care for cordovan. It has a stripping agent that could damage shell. Avoid the Mebane store.
I've used a product called "Leather honey" it is marketed as a conditioner for leather soles. It makes soles less susceptible to wear. You can also use it as a conditioner for upper, but I have other products for that. It does work and my soles hold up better vs. a pair of soles that I have not applied this conditioner to.
