I have used this on older snow boots that were starting to allow wet to seep in, UGG's, Bearpaws, sneakers & 2 pair of work shoes. Awesome results so far (now I don't purposely stomp in water).  The area on my garage floor where I sprayed all my shoes 100% repells water now.  **Spray outside & let stuff stay outside till recommended dry time, the odor stays around for a while.  I've sprayed about 7 pairs of shoes/boots & still have approx 1/3 bottle left.  I'd buy again to retreat next year.
