This stuff works best when used within say 10 days of using the footware - after that, the effect seems to wear off. So why a 5-star review? Soooo easy to use - just strip off your boot laces and load this stuff on the unlaced boot. (Pack it in the area around the boot-tongue interface.) I did not follow instructions - I held the spray head close to the boot and loaded on the spray. I did not notice any change in coloration of my boot - maybe a bit darker for a day or two, but that's it. (After all- they're hiking boots! So who cares if they're a bit darker after applying the spray.)One can of spray seems to be good for about 6 applications on over-the-ankle hiking boots (so maybe 4 applications for 10 inch-high boots). So one can is probably good for a season for one pair of boots. But load this stuff on where it counts - around the area where sole and boot meet, around the toe box, and around the area where the laces are over the tongue of the boot. One word of caution: APPLY THIS STUFF OUTDOOORS! And try to stay upwind of the spray. (The propellant did not agree with my lungs.)As for effectiveness, snow and water just rolled off of my boots after using this stuff. Like I said, it lasts about 10 days, but oh-what those ten days are! Better'n Gore-Tex! I used it on Ultra-suede-type leather, and that's probably where it does best. And speaking of Gore-Tex, I used this on boots with Gore-Tex liners and it did not in any way compromise the Gore-Tex - so no worries about mucking-up your Gore-Tex boots by using this product.There are lots of water repellants for honest-to-gosh cow-hide leather boots, but very few that work with Ultra-suede-type boots having Gore-Tex liners - this product is probably the best for that type of use, and as said before - sooo easy to use!

Ist super

Great stuff, works to keep our tennis shoes clean and waterproof for normal wear and tear and vacation travel. I use it on all my nice Diadoras and Sam Edelman tennis shoes. Hasn’t changed any of the colors of my shoes

Keeps water out while remaining breathable .

I tested this Spray on several materials, and the results were mixed—but very clear in terms of where this product shines.On suede, this spray works extremely well. I applied two coats, allowing proper drying time between applications, and the water repellency was excellent. Water beaded right off, and the suede’s texture and color were not negatively affected. For suede shoes or boots, this product is a definite winner.However, performance drops off significantly with more absorbent fabrics. I tried it on denim pants and applied three coats, but the material continued to absorb water. The spray didn’t create a protective barrier, likely due to how absorbent denim is. I had a similar experience with canvas after two coats, water still soaked through rather than beading on the surface.✅ Pros• Outstanding waterproofing for suede• Easy to apply• Doesn’t stiffen or visibly alter suede• Strong water beading after proper application❌ Cons• Ineffective on denim and canvas• Not a one‑solution‑fits‑all spray for fabrics
