My go-to closed-toe shoes are sporty maryjanes, but it's a style that doesn't really work with socks. So I keep shoe deodorizers on hand to keep my kicks smelling fresh. I normally use aerosol sprays or occasionally powders; this was my first time using a pump spray bottle. I like that this shoe deodorizer is made in the USA, and Red Moose seems to have a good reputation for leather-care products.This is billed as a "fragrance-free" product, and it doesn't have much of a scent -- but what little scent it has is not unpleasant. I'm honestly not sure what this is made from, as there are no ingredients listed on the bottle or on the manufacturer's website. The directions indicate that the spray should be applied and allowed to work overnight or at least for 12 hours. Since the liquid is a pump spray, it does leave insoles damp after spraying...you can't "spray and go" with this product.Does it work? It seems to, but I can't really tell for sure since it doesn't leave a fresh scent behind. I don't have particularly stinky feet, so I don't notice much of a difference before vs after use. I mainly use shoe deodorizers because I don't like it when my memory-foam insoles are damp with sweat; however, they end up staying damp when I spritz in this spray.I'd really like to see Red Moose disclose the ingredients. Since they specialize in leather care, I'm wondering if this shoe deodorizer is really intended more for leather insoles than fabric covered memory-foam. Though this seems to be a good product, my personal preference is for aerosol sprays or powders that I can apply shortly before wearing -- so that's why I'm rating this 4 stars.
