Just got my Beckmans in Cigar Featherstone. I have some Dr. Martens Wonder Balm that is still about half full from 8 years ago. Is this ok to use on my new boots? Coconut oil, lanolin, & beeswax are the ingredients. I sized down from what i usually wear in shoes. I have a pair of Johnston & Murphy dress shoes in 9, and my Beckmans are 8.5 and fit much better than the 9's I tried on first.
