Love this shoe cleaner! My boyfriend ordered it for a pair of suede chukka boots to keep them clean and I used it on a few pairs of cheap "suede" flats I got at Old Navy over a year ago and it really did make them look brand new! There was no discoloration, no coming apart of our shoes or anything bad like that; it's a gentle formula that literally just wipes away worn in dirt and stains on shoes. We have not had issues with this product what so ever, it does the job 100% and I will be buying again once we run out.
