What to use on Fly waxed leather boots

[Gran0laG1rl]

Preferably something suited to dark brown that might restore a bit of colour or redarken scuffed areas.

Ive just ordered some balm from Birkenstock, I have nubuck boots so am hoping to rub that in, its clear in colour

Shoe cream rather than polish is good for restoring colour, and you can use dubbin to re-wax the surface and protect them. Most shoe shops or Timpsons will have those things.
