Good for giving your shoes some water resistance. Recommend spraying it outside as it is strong and creates some over-spray. Dries quickly. Good to test for color fastness, but I did not have any problems.
Sprayed on sneakers in preparation for a day-trip to visit snow. Kept my feet dry even when feet sunk into 2-foot deep snow. Very strong chemical odor when applying, so must apply outdoors in well ventilated area and away from any open flame or spark (instructions warn it is highly flammable). Once shoes dried outside overnight the strong odor was not a problem.
I have used this product multiple times on running shoes,golf bag, lunch bag and the like. keeps stuff looking new and i think it goes pretty far and is less expensive than some other brands i have tried.
It is strongly advisable to apply this spray on waterproofer outside or in your garage and leave the shoes or item to dry overnight outside if possible since the initial odor is offensive but once dry it fades away.
