Hello, I wear leather dress shoes for work (school teacher) and they only last me a year or two before they are all scuffed up and need to be replaced (they take a good beating, sun/rain etc). Now doing some research, I cam upon many ways to condition/polish/wax etc your shoes to keep them going... and many many products one can purchase (Rad, but for shoes I suppose). Is there maybe one or two products that are "all purpose" that you would recommend that I could use for most shoes? Preferably colourless so that I can apply on both black and brown colours... does it exist? or am I dreaming? Thank you in advance.
