Yes, go ahead and use shoe trees. I use shoe trees in all of my welted and non-welted leather shoes. I understand they help keep the creasing down and aborb moisture from the shoe.
I'm not sure what happened here, but you are supposed to use a mix of water and vinegar to clean salt stains.
Yes, get shoe trees. A lot of shoes trees are made by Woodlore (Allen Edmonds, Jos A. Bank, Nordstrom). Every now and then Jos A. Bank has a buy one get two free sale. That is probably the best time to buy.
K will do, what about the other stuff though? I've been seeing that Saphir Renovateur
is a really good product. Would a process like this be good enough to keep my shoes clean and nice and shiny and looking new?
1.Clean/remove stuff using a horsehair brush(DO I ALSO NEED TO USE A CLOTH AFTER THIS?)
2.Use Saphir Renovateur all over the shoe, let dry for 3-5 minutes
3.Remove excess using horsehair brush
4.Buff out with cloth
Would that be good enough, or should I also use a polish?
