For odor control we recommend treating the shoes with an odor eliminator like MiraZyme™, which is a powerful blend of microbes used to remove odors caused by mold, mildew and bacteria.
The first thing we recommend is scrubbing the foot bed with a stiff brush. Many times an invisible film of bacteria will form on foot beds causing odor. We recommend that you break-up this film by first wetting the foot bed and then scrubbing it with a stiff brush.
Next, fill a container with just enough water to completely submerge the boots (about a gallon). Then add about 3 oz. of MiraZyme to the water and mix. Soak the boots in the MiraZyme bath and be sure to saturate them completely.
Once you've soaked the boots, remove them from the MiraZyme bath and allow them to air dry completely. Do not rinse the boots as rinsing may remove the microbes. Also, do not apply heat as heat may also kill the microbes. It is best to allow the boots to air dry as long as possible. This gives the microbes plenty of time to do their job. You will not notice a reduction in odor, until the item has air dried completely.
If you do not want to soak the boots or shoes, you can also mix a spray solution of MiraZyme, but this solution must be used withing 72 hours of mixing with water for maximum effectiveness.
Mix 2 oz. of MiraZyme with 16 oz. of water in a spray bottle. Spray the boots. The item does not need to be saturated with the MiraZyme solution, but should be noticeably damp. Allow to air dry.
