Socks for swollen feet – what you need to look out for

swollen feet

Socks for severely swollen feet should be specially designed to provide comfort and support without adding pressure that could cause pain or further swelling. Here are some Requirements for socks for swollen feet and legs

Requirements for socks for swollen feet and legs

  1. Material: They should be made of soft, breathable materials such as bamboo, merino wool or special moisture-wicking fibres to keep the foot dry and comfortable.
  2. Elasticity: High elasticity is important so that the socks can be easily pulled over swollen feet and adapt to the shape of the foot without constricting.
  3. Seamless: To avoid friction and irritation, seamless socks or socks with very flat seams are ideal.
  4. Wide waistband: A wide, non-constricting waistband prevents constrictions and promotes blood circulation.
  5. Cushioned soles: Extra cushioning can provide comfort, especially if your feet are sensitive or painful. Some knitted socks have a plush sole which can absorb shock and moisture.
  6. Compression: In some cases, light to moderate compression socks can be helpful to promote blood circulation and reduce swelling. However, it is important that the compression is appropriate and, if possible, recommended by a doctor.
  7. Size and fit: The socks should be available in different sizes to ensure an optimal fit. A good fit is crucial to avoid pressure points and increase comfort.
  8. Ease of putting on and taking off: Socks designed specifically for people with mobility impairments or limited dexterity may have additional features that make them easier to put on and take off.
  9. Moisture management: Good moisture management helps to keep feet dry and reduces the risk of blisters and other skin irritations. Merino wool is a real champion here, as it can absorb 30-40% of its own weight in moisture – significantly more than cotton, for example. This keeps your feet dry for longer.

It is always advisable to seek advice from a specialist for specific medical conditions or severe swelling in order to find the most suitable socks.

Bolter Socks offers vein socks made from merino wool that are precisely tailored to these needs and can provide good comfort for people with water retention in the feet and legs or feet that are swollen for other reasons. Vein socks with copper threads are also available for people such as diabetics or those with concomitant circulatory disorders.

Possible reasons for (severely) swollen feet

Swollen feet can be caused by a variety of things, ranging from temporary conditions to serious health problems. Here are some of the most common reasons for swollen feet:

  1. Standing or sitting for long periods: Standing or sitting for long periods, especially on long flights or car journeys, can affect circulation and lead to swelling.
  2. Overweight: Being overweight puts additional pressure on the legs and feet, which can lead to swelling.
  3. Age: As you get older, the veins in your legs can work less efficiently, which can lead to swelling.
  4. Pregnancy: During pregnancy, the increased pressure on the blood vessels in the pelvis and legs can lead to swelling. This is usually normal, but in some cases can indicate pre-eclampsia, a serious condition.
  5. Injuries: Sprains, fractures or other injuries to the feet or legs can lead to swelling.
  6. Medication: Certain medications, including blood pressure medications, steroids, antidepressants and non-steroidal anti-inflammatory drugs, can cause swelling as a side effect.
  7. Infections: In people with diabetes or other conditions that affect the immune system, infections on the feet can lead to swelling.
  8. Venous insufficiency: A weakness or malfunction of the venous valves in the legs can lead to blood congestion and consequently to swollen feet.
  9. Lymphoedema: A build-up of lymph fluid due to problems with the lymphatic system can lead to swelling, especially in the legs and feet.
  10. Heart, liver or kidney disease: These conditions can affect fluid regulation in the body, which can lead to swelling in the legs and feet.
  11. Blood clots: Blood clots in the legs can obstruct blood flow and cause swelling. Deep vein thrombosis (DVT) is a serious condition that requires immediate medical attention.

It is important to note that swollen feet can be a symptom of an underlying medical condition. If the swelling occurs suddenly, is accompanied by pain, occurs in only one foot or other worrying symptoms are present, a doctor should be consulted to determine the cause and recommend appropriate treatment.
