FAQs: Can You Tumble Dry Trainers?

After a wet run, muddy walk, or an unexpected downpour, it’s tempting to toss your trainers straight into the tumble dryer and be done with it. Quick, easy, and done in an hour—what’s not to like?

Unfortunately, quite a lot.

This FAQ guide explains when (if ever) you can tumble dry trainers, what risks are involved, and the safest ways to dry them without ruining their fit, cushioning, or lifespan.

Can you put trainers in the tumble dryer?

Technically yes—but you really shouldn’t.

Most trainers aren’t designed to handle the heat and mechanical stress of a tumble dryer. Even a single cycle can:

• Warp the shape of the shoe
• Damage adhesives that hold the sole together
• Shrink or stiffen materials
• Reduce cushioning performance

In short: it’s a fast way to shorten the life of your shoes.

What happens if you tumble dry trainers?

Putting trainers in the dryer can lead to several common problems:

1. Heat damage

Modern trainers rely heavily on glues and synthetic materials. High temperatures can weaken adhesives, causing soles to separate or uppers to deform.

2. Structural warping

The tumbling motion repeatedly throws shoes against the drum, which can distort their shape—especially around the toe box and heel counter.

3. Cushion breakdown

Foam midsoles (like EVA) can lose their responsiveness when exposed to heat, making your shoes feel flat and less supportive.

4. Noise and machine damage

Trainers banging around inside the dryer aren’t just loud—they can damage the drum over time.

Are there any trainers that can go in the dryer?

Some trainers are more durable than others, but very few are truly dryer-safe.

If you’re considering it anyway, only proceed if:

• The care label explicitly allows machine drying
• The shoes are made from simple materials like canvas
• You use low or no heat settings

Even then, it’s still a risk—not a recommendation.

Can you tumble dry trainers on low heat?

Low heat is safer—but not safe.

Lower temperatures reduce the risk of melting adhesives or shrinking materials, but they don’t eliminate it. The tumbling action alone can still deform the shoe.

If you absolutely must:

• Use the lowest heat or air-only setting
• Place shoes in a laundry bag or pillowcase
• Add towels to cushion impact

But again, this is damage control—not best practice.

What’s the best way to dry trainers?

The safest method is simple: air drying.

Step-by-step:

1. Remove insoles and laces
   This helps everything dry faster and more evenly.
2. Stuff with paper or towels
   Use newspaper or dry cloths to absorb moisture and maintain shape.
3. Place in a well-ventilated area
   A warm, dry room works best.
4. Avoid direct heat sources
   Don’t place them on radiators or in direct sunlight—this can cause similar damage to a dryer.

How long do trainers take to air dry?

Typically:

• 12–24 hours for lightly damp shoes
• 24–48 hours for fully soaked trainers

Factors like humidity, airflow, and material type will affect drying time.

Can you speed up the drying process?

Yes—without using a dryer:

• Use a fan to improve airflow
• Replace stuffing material every few hours
• Position shoes near (not on) a gentle heat source
• Use silica gel packs or moisture absorbers

Patience here pays off in longer-lasting shoes.

Can you dry trainers overnight?

Sometimes—but don’t rely on it.

If they’re only slightly damp and you:

• Remove insoles
• Stuff them properly
• Place them in a ventilated space

…they might be dry by morning. Otherwise, expect another day.

What about putting trainers near a heater?

Better than a dryer—but still risky.

Direct heat can:

• Crack materials
• Warp soles
• Dry out cushioning foam

If you use a heater, keep shoes at a safe distance and allow gradual drying.

Should you ever tumble dry trainers?

Only as a last resort.

If you’re in a hurry and willing to accept the risk, you can minimize damage—but you can’t avoid it entirely.

For most people, it’s simply not worth it.

Final takeaway

Tumble drying trainers might seem convenient, but it often leads to:

• Reduced comfort
• Shortened lifespan
• Permanent damage

Air drying remains the safest, most effective method.

If you invest in good footwear—especially for walking, running, or all-day wear—it’s worth taking the extra time to dry them properly.
