I recently had a reader reach out with a question that I thought might be helpful to others. The question, can you spray DWR on trail runners? DWR, or Durable Water Repellent is a spray that has become very popular for waterproofing outdoor gear and equipment. But how well does Durable Water Repellent spray work on trail running shoes, will it actually make your shoes waterproof, and what are the overall advantages / disadvantages? Below I’ll give you all of the info you need to know about using waterproofing spray on trail runners.
Can you spray DWR on trail runners?
Yes, you can spray DWR (durable water repellent) on trail runners. But no, it is not going to make your shoes waterproof. Trail running shoes are typically made from mesh and other weaves for breathability. So it would be like using a waterproof spray on a window screen.
What the DWR spray will do is make the actual show material and mesh water resistant. Offering several advantages, including reducing the amount of moisture that is held in the material, while also reducing mud and ice build up. Which can be advantageous for runners based on the time of year you are running. And there are plenty of runners that do this.
The negative DWR coats the fabric is a “hydrophobic” coating which will add weight to the shoe. Not a lot, but this may negate the weight you save from holding less moisture. The sprays also don’t seem to last very long. Expect to have to spray them down before almost every run. So don’t expect them to protect for the length on an ultra.
The Pros
- Reduces moisture build up in the shoes material and mesh
- Helps reduce mud build up on the shoes upper
- Drastically reduces ice build up on the shoes upper
The Cons
- Adds weight to the shoes
- Does not last long
- Will not waterproof your shoes
How to Use Waterproof Spray on Your Running Shoes
When applying DWR to your trail running shoes, be sure to follow any manufacturer’s instructions carefully.
Typically, you will need to clean and dry the shoes thoroughly before applying the DWR spray. Then, simply spray the shoes evenly, making sure to cover all areas. After applying the spray, allow the shoes to dry completely before wearing them.
Conclusion – Can you spray DWR on trail runners?
In conclusion, using a DWR spray on trail runners has several benefits. It can reduce moisture build-up in the shoes’ material and mesh. Additionally, it can help reduce mud build-up on the shoes’ upper and drastically reduce ice build-up, making your runs safer and more comfortable. However, it’s important to consider the cons before using a DWR spray. Applying the spray can add weight to your shoes, which can negate the weight savings from moisture. And it doesn’t last very long. Furthermore, DWR won’t completely waterproof your shoes. If that’s something you’re looking for, check out Gortex shoes. Therefore, it’s up to each individual to weigh the pros and cons and decide whether using a DWR spray on their trail runners is worth it for them.
