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 .

Great product that protects quality shoes for a long time.

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

worked great in sealing my tent, easy to apply!
