first, the bottle is so small and way too costly, secondly it states to saturate the shoe, being that it is liquid it runs all over the plce and half of the liquid was on the floor, thirdly it just does not work.  I used this entire bottle on 3 pairs of shoes and wore them for  the 15 mins that was required, the next day they were the same as before and I was out the liquid and my money.
