Electric Boot Dryer

Damp Liners Are Cold Liners

A boot liner absorbs sweat throughout a day and does not dry on its own overnight in a cold room, which means starting the next day in damp boots.

Damp insulation conducts heat away from the foot far faster than dry insulation, so a wet liner is a cold liner regardless of how warm the boot is rated.

That is why cold feet frequently get worse across a week rather than better, which people attribute to weather rather than accumulated moisture.

Warm Air Not Hot Air

Boot liners and shells are damaged by heat, and a liner dried on a radiator or with a hot air blower shrinks, hardens and loses its fit.

Purpose-made dryers run warm rather than hot for exactly that reason, and they take longer than a heat source and do not destroy the boot.

Drying boots in front of a fire or on a hot radiator is a genuine way to ruin an expensive fitted boot permanently.

Airflow Versus Passive Warmth

Units that blow air through the boot dry considerably faster than passive warm rods, since moving air carries moisture away rather than merely warming it.

Passive units are silent and cheap and take much longer, which for an overnight cycle is frequently sufficient.

Timers on better units prevent a boot being warmed all night, which is unnecessary once dry and wastes electricity.

Gloves, Helmets And Everything Else

Most dryers include attachments for gloves, which are the other item that never dries overnight and that being damp ruins a day.

Helmet liners, base layers and socks all benefit, and a unit with several ports handles a household rather than one person.

For a family, that multiplies the value considerably, since drying four pairs of boots and eight gloves is otherwise not possible in a hotel room.

Odour And Hygiene

Damp boot liners grow bacteria, which is where boot smell comes from, and drying them thoroughly reduces it far more than any spray does.

Some dryers include ultraviolet or ozone treatment marketed for sanitising, and the evidence for these is weaker than for simply drying properly.

Removing liners from shells overnight dries both faster and is worth doing regardless of what dryer is used.

Travel versions run from a car socket or fold small enough for a suitcase, which for a week in accommodation without drying facilities is the whole point. Many hotels and chalets provide drying rooms, and those rooms are frequently too hot and too crowded to dry anything properly. Carrying a small unit removes the dependence on whatever the accommodation happens to offer.

Noise is worth checking for anything running overnight in a bedroom, since some fan units are considerably louder than a product photograph suggests.

Port count determines whether a unit serves one person or a family, and four ports handles two people with boots and gloves where two ports handles one.

The Verdict

A small appliance that solves a real and unpleasant problem, where warm rather than hot air protects the boots.

Hot heat sources damage liners permanently, passive units are slow, and sanitising claims are weakly supported.

Never dry boots on a radiator. Heat shrinks and hardens the liner and ruins an expensive fit.
