Leaking Wellies

Do my Wellington Boots Leak?

Maybe, but it could just be perspiration.

In fact we all perspire. Our bodies are covered in sweat glands and the 250,000 sweat glands on the soles of our feet are responsible for as much as half a pint of moisture each day, even at rest. With the addition of physical activity or hot, humid weather the amount of perspiration can increase twofold.

The sweat glands which cover our body have a higher density on the palms of the hands and the soles of the feet. This moisture usually evaporates from the skin’s surface to help regulate body temperature.

Wearing shoes inhibits the process of evaporation, and waterproof rubber boots can be particularly obstructive, allowing only about 50% of moisture to be released through the top of the boot.

Although many wellington boots have a breathable lining which draws moisture away from the foot, most of these linings will struggle to keep the foot completely dry in all circumstances.  A leaking boot is a failure in the manufacturing process and it is unlikely to affect both boots.  If both boots do feel damp it can probably be attributed to perspiration build-up from the wearer.

Having their Wicked Way…

The lining made from Merino sheepskin which is used in the Thorn and Field wellington boot is excellent at managing the boots ‘climate’, especially when worn directly against the skin. The natural super fine fibre draws moisture away from the skin, known as wicking and this helps prevent clamminess.

Merino wool fibre is able to absorb up to 35% of its own weight in moisture. Due to its effectiveness at wicking, the fibre will occasionally seem damp to the touch when the boot has been worn for a long period of time or for strenuous physical activity. This sensation can sometimes be mistaken for a leak in the rubber outer but is generally where the absorbed moisture has cooled, causing the feeling of dampness.

Removing the insoles and airing the boots in a warm, dry room will allow the Merino Sheepskin to dry out.

Testing for a Leak

• If you suspect that the rubber outer has failed, remove the insoles and allow the boots to dry for 24 hours in a warm place (do not apply direct heat).
• Feel inside the boot and make sure that they are dry.
• Fill a bucket or bath with water.
• Put your boots on without socks so your feet can feel any water entering the boot.
• Stand in the bucket or bath water and flex your foot to simulate walking.
• If there is a leak you should feel the water entering the boot almost immediately.
• The Thorn & Field wellington boots are guaranteed for 12 months from the date of purchase. The boots should withstand general wear and tear, and are covered against manufacturing defects. If you do find a fault or have a reason for complaint, please email sales@thornandfield.com.
