This product does two things very well.
1. Seems to help rubber stick to the wall, especially those really textured gym walls. It doesn’t really feel different to my hand when I touch it, but I felt that I got more slab performance out of my shoes.
2. Cleans the rubber and restores it to a deep black. This is pretty qualitative, but getting the dirt, chalk, and other mush off your shoes and leaving them a nice black color makes your shoes look new even if they smell old.
4/5 stars because I’m not really sure what is in this stuff and it smells flammable.
