Using mink oil on your leather goods is a must in the climate I live in. There is always snow, ice or water in my path.  I purchased some Chippewa boots for casual wear and needed to protect them.  Just followed the directions, rub on, then rub off.  Buff with a cloth or brush, if desired.
I noticed an immediate difference in the softness and flexibility of the leather after application.  Its very nice!  Also, just remember this stuff darkens the leather!  If you like the color of your shoes now, this might not be the best product.  I wanted to darken and even the color of my Chippewa's.  With the help of Camp Dry mink oil, they are the perfect dark brown.
The only reason for the 4 rather than 5 stars is that I don't know how often I'll have to re-apply the oil.
