Trail Running Kit Care Guide

Muddy, wet winter running is hard on trail shoes, jackets and running vests. Cleaning and drying your kit properly after each run protects grip, waterproofing and fit, so every piece lasts longer and needs replacing less often.

Winter trails combine mud, standing water, grit and cold, and that mix wears kit faster than dry summer running. Mud packed into the tread (the grooved pattern on the sole that grips the ground) reduces traction. Grit inside the shoe rubs against both your foot and the material. Damp kit left in a bag also grows bacteria, which causes lingering smells. A few minutes of care after each run prevents most of this wear.

Fresh mud rinses off far more easily than dried mud, so clean your trail shoes as soon as you get home.

• Remove the insoles. The insole is the removable cushioned layer inside the shoe. Rinse it separately.
• Rinse the tread. Use cool water to clear mud, clay and stones from the sole. Clean tread keeps grip strong for your next run.
• Scrub the upper. The upper is the fabric part that covers your foot. A soft brush and cool water remove grit that wears the material, especially where the shoe flexes.
• Keep the pressure low. A hose on a gentle setting or a garden pump sprayer works well. A high-pressure jet held close can damage foam and glue.
• Wash muddy laces by hand. Fresh laces are also an easy way to refresh a worn pair.

Waterproof trail shoes need the same care. Dirt can block the waterproof membrane (the thin layer that keeps water out while letting sweat escape), which reduces breathability. Browse waterproof running shoes if your current pair no longer keeps water out.

Heat damages trail shoes, so dry them slowly at room temperature. Radiators, airing cupboards and tumble dryers can weaken glue, stiffen materials and shrink the shoe.

1. Take out the insoles and dry them separately.
2. Loosen the laces and pull the tongue forward to open the shoe.
3. Pack the toe and sides with crumpled plain paper or kitchen roll. Newspaper also works, although the ink can stain light-coloured uppers.
4. Swap the paper once or twice until it comes out nearly dry.
5. Leave the shoes in a well-ventilated room, away from direct heat and sunlight.

Rotating two pairs of trail running shoes gives each pair a full day to dry between winter runs.

Baking soda absorbs the smell of trail shoes that have sat damp for too long. Sprinkle a generous layer inside each shoe, leave it overnight, then tip it out the next morning. This method is cheap, quick and free of harsh chemicals.

Standard detergent often struggles to remove odour from technical fabrics such as polyester and nylon. A sports wash is made to break down the sweat and bacteria that cause those smells. It also protects the fibres that move sweat away from your skin.

Avoid fabric softener on running kit, because it coats technical fibres and reduces how well they wick (draw moisture away from the body). Waterproof jackets benefit from a technical wash too. Dirt and body oils weaken the DWR coating (durable water repellent, the finish that makes rain bead off the fabric), so a clean running jacket sheds water better.

A clean running vest stays flexible and avoids the white salt marks that build up from dried sweat.

• Empty the pockets. Remove soft flasks, the water bladder and any food wrappers.
• Check the care label. Many vests suit a hand wash in lukewarm water or a gentle 30°C machine cycle, but the label for your vest always comes first.
• Rinse thoroughly. Salt left in the fabric stiffens the material and causes white marks.
• Air dry. Hang the vest away from direct heat and skip the tumble dryer.
• Dry the bladder open. Rinse the bladder and flasks after each run, then hang them open to stop mould forming.

Shop hydration vests if your current pack has lost its shape or its fit.

Replace trail shoes when the lugs (the raised rubber studs on the sole) look worn flat, the midsole (the foam layer that cushions each step) feels flat or creased, or your foot slips inside. Many runners replace trail shoes after 300 to 500 miles, although terrain and body weight change that number. Read why trail running shoes matter for more on grip, protection and fit.

Short winter days mean many runs start or finish in the dark. A head torch lights the trail, and a hi-vis layer helps drivers and cyclists spot you on road links. Warm gloves and running tights keep you moving when temperatures drop. Our trail running kit list covers every piece of kit by season and terrain, and our guide to running in the rain helps you layer for wet weather.
