I've been using this on my FRYE Vintage Boots for almost 2 years now. This is a 'Pump' bottle, not an aerosol so it's eco-friendly. It puts natural oils and waxes into the leather, keeping it supple while still allowing it to breath. It also makes your leather water 'Resistant', although I wear my boots in the rain with no problems. Even my shoemaker commented on the excellent condition of the leather saying 'They'll last forever'.  I also use it on my black leather jacket,  the leather parts on running shoes, wallet, 'Indiana Jones' hat, leather office chair and more.  If it's leather this will work.  There's one drawback.. I wouldn't recommend this for highly polished shoes.  It make it difficult (not impossible though) to get a high shine.  Highly recommended!
