Didn't work for me. 3 treatments, marginal improvement.
MY shoes got wet in the rain one day and started smelling awful after that. I applied this product, thought the smell improved, but that next night they were just as bad as the previous day. I applied again, machine washed and dried, and applied again (leaving outside to dry), and the smell just doesn't disappear. Not what I expected from this product.
