As with all waterproof products, boots, jackets, gloves, etc., regular upkeep with a Durable Water Repellant (DWR) is necessary.
For leather products, we recommend Otterwax Boot Wax to help condition the leather and to maintain water repellency.
For non-leather products, you can use a product such as Nixwax Spray.
Both of the above-mentioned products are available on our website here but other products can be substituted if used according to label directions.
