Learn the best way to clean, dry, and maintain your Altra GTX trail shoes. Keep the waterproof membrane working and extend the life of your footwear.
Quick Answer
To keep your Altra GTX trail shoes performing, clean them with mild soap and water, air-dry them away from heat, and reapply a waterproofing treatment when needed. Avoid machine washing and direct heat to protect the GORE-TEX membrane.
Why regular care matters for GTX shoes
Altra GTX trail shoes, like the Timp 5 GTX, use a GORE-TEX upper that is durably waterproof, windproof, and breathable. Dirt and mud can clog the membrane's pores, reducing breathability and trapping moisture inside the shoe. Regular cleaning keeps the membrane working as intended.
The Vibram Megagrip outsole on many Altra GTX models is designed for grip on wet and rugged terrain. Keeping the outsole free of caked mud and debris helps maintain traction and prevents premature wear.
What to avoid: common mistakes
Machine washing and drying can damage the GORE-TEX membrane and the shoe's construction. The agitation and heat can break down the waterproof layer and weaken adhesives.
Do not use harsh detergents, bleach, or fabric softeners. These can strip the durable water repellent (DWR) finish and harm the membrane.
Never dry GTX shoes on a radiator, near a fire, or in direct sunlight. High heat can warp the shoe and degrade the waterproofing.
Step-by-step cleaning and care routine
- Remove loose dirt and debris: After each run, knock the shoes together or use a soft brush to remove caked mud and dirt from the outsole and upper. Pay attention to the tread grooves to maintain grip. Check the tread for small stones that can become embedded.
- Prepare a mild cleaning solution: Mix a small amount of mild soap (like dish soap or a dedicated shoe cleaner) with lukewarm water. Do not use hot water, as it can damage the membrane. Avoid detergents with bleach or fabric softener.
- Hand-wash the shoes: Dip a soft cloth or brush into the soapy water and gently scrub the upper and outsole. Work in small circles, focusing on stained areas. Do not submerge the entire shoe in water. Submerging can force water into the shoe and degrade the membrane.
- Rinse with a damp cloth: Use a clean cloth dampened with plain water to wipe off soap residue. Ensure no soap remains, as it can attract dirt and reduce breathability. Residual soap can also degrade the DWR finish over time.
- Air-dry away from heat: Stuff the shoes with newspaper or a dry towel to help them hold shape and absorb moisture. Place them in a well-ventilated area at room temperature, away from direct sunlight and heat sources. Replace the newspaper if it becomes damp to speed up drying.
- Reapply waterproofing treatment (when needed): After the shoes are completely dry, apply a waterproofing spray or treatment designed for GORE-TEX footwear. This helps restore the DWR finish that causes water to bead up on the surface. Test the treatment on a small area first to ensure it doesn't discolor the upper.
