Here's a question I can't find the answer to anywhere I look. Should I regularly condition the bottom of a leather soled shoe at all / just as often as I condition the upper of the shoe? If I'm going to buy a pair of Crocket and Jones how should I treat the outsole? I found 1 youtube video from Wolverine recommending applying conditioner to the bottom and edge of the outsole but this is the only place I have seen this done. If you get a shoe shine, the only thing they apply to the outsole is edge dressing. What do you recommend for taking care of the outsole of new and used shoes leather soled shoes? Thanks!
