The activated bamboo charcoal binds moisture and odor molecules, while the salt minerals neutralize the pH level in the shoe. Without moisture, bacteria lack the conditions they need to thrive – odors don't even have a chance to develop. Simply place one cushion into each shoe after wearing them and leave them to work overnight.

With regular use, up to 4 months. After that, the absorption capacity of the natural filling is exhausted and the pads should be replaced with new ones – so one pair will last you through half a sports or hiking season.

Sprays cover up odors with fragrances and introduce additional moisture and propellants into the shoe. DUFFIES® tackle the root cause: they remove the moisture from the shoe where odor-causing bacteria grow in the first place – without aerosols, without silver ions, without chemical bactericides.

For everyone: hiking shoes and boots, sports shoes, football boots, running shoes, golf shoes, work shoes, and everyday footwear. Furthermore, the cushions also combat musty odors in gloves, sports bags, lockers, cupboards, suitcases, and in the car.

Yes. DUFFIES® consist of a purely natural filling. All ingredients comply with the European Union's REACH regulation, tested in cooperation with Bureau Veritas.

After wearing, insert one cushion into each shoe and leave them to work overnight. By the next morning, the shoes will be dry and fresh. Between uses, it is best to store the cushions in a dry place – this allows you to make full use of their effective lifespan of up to 4 months.
