Cold Feet: Causes, Warning Signs and What to Watch With Compression Stockings

Cold feet are usually harmless. When you are cold, the small blood vessels in your feet and hands narrow so your body loses less heat. But if your feet stay cold all the time, only on one side, or look pale or feel numb, a medical condition may be behind it, such as a circulation disorder of the leg arteries, Raynaud's syndrome, an underactive thyroid or vascular damage from diabetes. If you wear compression stockings and your toes turn blue, white or numb, take the stockings off straight away and have it checked by a doctor.

Key Takeaways

• Normal: In the cold, the small blood vessels in your feet and hands contract. This eases once you warm up.
• Possible causes of feet that stay cold: a circulation disorder of the leg arteries (peripheral artery disease, PAD), Raynaud's syndrome, an underactive thyroid, vascular damage from diabetes.
• Call 112 at once (the emergency number in Germany and the EU) if a leg suddenly hurts badly and turns deathly pale, cold and numb.
• With compression stockings: according to the German guideline, toes turning blue or white, numbness, increasing pain, shortness of breath, breaking out in a sweat or suddenly restricted movement mean: take the stockings off straight away and have a doctor check it.
• Before compression, a doctor must check whether you have advanced peripheral artery disease. If you do, compression is contraindicated according to the guideline.

Why Do Feet Get Cold?

Your feet and hands are furthest from the core of your body. When you are cold, the small vessels there narrow so your body loses less heat. This is a normal protective response. Warm socks, movement and a warm room bring the warmth back.

Pay attention if your feet stay cold even when you are warm, if only one side is affected, or if your skin, sensation or pain changes.

Possible Causes of Feet That Stay Cold

Peripheral artery disease (PAD)

In peripheral artery disease, known in German as "Schaufensterkrankheit", the arteries in the legs are narrowed. According to Germany's federal health portal, signs of poor circulation can include:

• a cold leg or a cold foot
• pale, bluish mottled, thin skin
• tingling or numbness
• slower hair growth on the legs
• cramp-like calf pain when walking that eases when you stand still

PAD often causes no or only mild symptoms for a long time. Have a doctor check for it, especially if you smoke or have diabetes, high blood pressure or high blood lipids.

Raynaud's syndrome

In Raynaud's syndrome, the small vessels narrow so much in the cold or under stress that hardly any blood reaches the fingers or toes. They turn pale to white, numb and cold. This is usually harmless and passes as you warm up. Sometimes, though, another condition is behind it, so have a doctor check frequent or severe attacks.

Underactive thyroid

When the thyroid makes too little hormone, the metabolism slows down. Feeling cold and sensitivity to cold are possible symptoms, along with tiredness, weight gain and constipation. Many of these symptoms have other causes too. A blood test at your GP's practice can clarify this.

Diabetes

Persistently high blood sugar can damage the blood vessels and nerves in the feet. With vascular damage, the foot often feels cool, the skin is pale or bluish and the pulse in the foot is barely detectable. With nerve damage, people feel cold, heat, pressure and pain less. If you have diabetes, have a doctor examine your feet regularly.

Warning Signs: When to Act Straight Away

• Call 112 at once: A leg suddenly hurts badly and is deathly pale, cold and numb. This can be an acute blockage of an artery.
• Under compression stockings: Your toes turn blue or white, you feel tingling or numbness, the pain increases, you become short of breath or break out in a sweat, or you suddenly cannot move your leg as well. Take the stockings off straight away and have a doctor check it. If you are very short of breath, call 112.
• See a doctor the same day: Your leg hurts even at rest, especially when you raise it, or blue to black patches appear on your toes.
• See a doctor soon: Cold feet on one side only, calf pain when walking, wounds on the toes or heel that heal poorly. If you have diabetes, have even small wounds and pressure marks on your feet looked at promptly.

Cold Feet With Compression Stockings

Not for everyone: check the arteries first

Compression presses on the leg from the outside. According to the German guideline on compression therapy, advanced peripheral artery disease is a contraindication, as is severe, decompensated heart failure. With severe sensory disturbances in the legs or advanced nerve damage, for example from diabetes, the benefits and risks are weighed up. That is why a medical examination comes before compression. If your feet are already cold all the time, tell your doctor.

Fit: the stocking must not constrict

According to the guideline, compression stockings can cause pressure damage to skin and nerves if they are not used properly. A stocking that cuts in, wrinkles or is the wrong size does not belong on your leg. Measure your size as described in our guide to measuring calf circumference, or have your legs measured at a medical supply shop (Sanitätshaus). If your doctor changed your compression class and your toes have been cold since, mention it.

Open toe and warmer layers

• Open toe: With open-toe models, the toes stay free. This makes the stocking easier to put on and is more comfortable for sensitive toes.
• A layer on top: A loose sock that does not constrict, worn over the compression stocking, can keep your feet warm. It must not add pressure.
• Material: Some compression stockings have cotton in the yarn. Trying them on is the best way to find what feels comfortable.

Movement

According to the guideline, compression only works properly when you move and your calf and ankle muscle pumps are working. Foot circles, rocking from heels to toes and walks get your feet going. You will find exercises in our vein exercises.

What Helps With Cold Feet in Everyday Life

Once a medical condition has been ruled out, simple things help:

• Keep warm: warm socks and shoes that do not pinch
• Move: get up now and then, do foot circles, take the stairs
• Don't smoke: smoking is an important risk factor for circulation disorders of the leg arteries

Which Doctor Should You See?

Start with your GP. They can check the pulse and circulation in your feet, test your thyroid and blood sugar, and refer you on if needed, for example to a vascular medicine specialist (angiology) if a circulation disorder is suspected, or to a vein specialist (phlebology) for veins and compression.

FAQ: Cold Feet

Why are my feet always cold?

Often it is a normal reaction to cold: the small blood vessels in your feet narrow to save heat. If your feet stay cold even when you are warm, a circulation disorder of the leg arteries, Raynaud's syndrome, an underactive thyroid or diabetes may be behind it. Your GP can find out.

When are cold feet dangerous?

If a leg suddenly hurts badly and turns deathly pale, cold and numb, it is an emergency: call 112. See a doctor soon about cold feet on one side only, calf pain when walking or poorly healing wounds.

Can compression stockings cause cold feet?

A stocking that is too tight or cuts in can press and cause harm. If your toes turn blue, white or numb, take the stockings off straight away and have a doctor check it. If the stocking fits well and your toes still stay cold, see a doctor about that too. A circulation disorder must be ruled out.

Can I wear compression stockings if I have cold feet?

That needs to be clarified by a doctor. According to the guideline, advanced peripheral artery disease is a contraindication for compression. If your feet are already cold all the time, tell your doctor before you start compression.

Does an open toe help with cold toes?

An open toe leaves the toes free and is often more comfortable for sensitive toes. It does not fix a circulation disorder. If your toes stay cold or turn pale, have a doctor check it.

What is Raynaud's syndrome?

In the cold or under stress, the small vessels in the fingers or toes narrow so much that they turn white, numb and cold. This is usually harmless and passes as you warm up. Sometimes another condition is behind it, so have frequent or severe attacks checked.

The Bottom Line

Cold feet are usually a harmless reaction to cold. But if they stay cold all the time, only on one side, or come with pain, pallor or numbness, have the cause checked. If you wear compression stockings, watch your toes: blue, white or numb means take them off and have a doctor check it, and the same goes for shortness of breath or breaking out in a sweat.
