If your feet are permanently cold from October onwards, you have our sympathy - and, more usefully, five things that actually work.
Cold feet aren't only uncomfortable. Left to it, winter brings chilblains, stiffness, numbness and aching joints, and none of that makes for a good walk or a pleasant evening in. The good news is that most cold feet are a solvable problem, and the solution rarely costs much.
The short version: get the blood moving, layer without squeezing, keep your feet dry, wear footwear with room in it - and choose a sock that insulates rather than just covers.
That last one does most of the heavy lifting, and it's the one most people get wrong.
Skip ahead:
1. Circulation 2. Layering 3. Staying dry 4. Footwear 5. The right socks Questions
1. Boost circulation - how to warm cold feet up
Cold feet are very often a blood-flow problem rather than a temperature problem. If circulation to your extremities is sluggish, no amount of insulation will help - there simply isn't enough warm blood arriving to insulate. So the first job is to get things moving.
Gentle foot exercises and a warm soak both work, and they take about five minutes. Here's the routine:
The eight steps in the video
- Put your socks on first - warm the feet before you work them
- Ankle dorsiflexion and plantarflexion - toes pointing away, then towards you
- Active straight leg raise
- Curl, flex and extend your toes
- Ankle circles, clockwise and anticlockwise
- Massage the LIV3 acupressure point
- Massage the SP6 acupressure point
- Squeeze the foot, heel to toe and toe to heel
Then keep that blood flowing rather than choking it off at the ankle. This is where a lot of people quietly sabotage themselves: a tight elasticated sock top restricts the very circulation you've just worked to improve.
Pair the exercises with a pair of loose topped socks. With no elastic gripping the top of the calf, blood flows freely into the foot - which is exactly what you want if your feet run cold, if your ankles swell, or if you're on your feet all day. Our Sussex is the one most people start with, and it's our best-selling sock for good reason.
2. Layer wisely - but don't squeeze
Layering socks works on the same principle as layering anything else: it's the trapped air between the layers doing the insulating, not the fabric itself. But there's a catch, and it's the one people fall foul of. If the extra layer makes your boot tight, you've just compressed the air out and squeezed your circulation at the same time. You'll end up colder, not warmer.
So layer only if there's genuinely room in the footwear - and use a thin base layer rather than two thick socks.
On a recent expedition to Svalbard, Norway - about 600 miles from the North Pole — Paul Freeman takes you through exactly how he layers, using our Surrey socks as the base layer. If it works at that latitude, it will manage a February morning in Northumberland.
The layering pair: Surrey as a thin base next to the skin, with a thicker Derbyshire over the top. Read the full story in 600 miles from the North Pole.
3. Keep your feet dry - this matters more than you'd think
Damp feet feel dramatically colder than dry ones, and the reason is physics rather than imagination. Water conducts heat far better than air does, so four things happen at once:
- Heat transfer. Water on the skin pulls heat away from your body much faster than air would.
- Evaporative cooling. As that water evaporates it needs energy, and it takes it as heat - from your skin.
- Lost insulation. Dry fabric works by trapping air. Wet fabric stops trapping air and starts conducting heat away instead, so a soaked sock is worse than no sock at all.
- Nerve sensitivity. Your feet are packed with temperature-sensitive nerve endings. Rapid heat loss sets them off, and your brain amplifies the whole thing.
Put those together and you have the reason a damp foot feels so much colder than the thermometer says it should. Which is why the fibre matters: cotton absorbs moisture and holds it against the skin, while mohair moves it away and dries quickly.
One myth worth dispelling while we're here - most people assume wet feet cause blisters. This rather good video shows that it isn't so simple:
4. Invest in footwear with room in it
Insulated, waterproof footwear is worth the money if you're outdoors in winter. But the single most overlooked detail isn't the lining - it's the fit.
Boots that fit snugly in summer will be too tight once you add a proper winter sock, and a tight boot means compressed insulation and restricted blood flow. If you're buying winter boots, buy them wearing the socks you actually intend to wear in them. It sounds obvious. Almost nobody does it.
Wellingtons deserve a special mention, because rubber is a poor insulator and most wellies have very little lining at all - meaning the sock does nearly all the work. We've written about that separately in the best socks for wellington boots.
5. Choose the correct socks
This is the one that makes the biggest difference, and it comes down to two questions:
- Indoors or outdoors? Cold feet on the sofa and cold feet on a hillside are different problems with different answers.
- How much room is there in your footwear? A thick sock is only warmer if it isn't being squashed.
Here are the four we'd point you at, depending on the answer.
Where are your feet cold? Pick the sock
| Where you're cold | The sock |
|---|---|
| In the house, or in bed | Bed Socks |
| In walking boots, on the hill | Derbyshire |
| In smart shoes, or where a thick sock won't fit | Sussex |
| Layering under another sock | Surrey |
| In wellingtons | Yorkshire or Northumberland |
| In trainers and everyday shoes | Ayrshire |
Between sizes? Our UK sock size guide takes a minute - and with winter socks, a size too small is a cold foot, because you've squeezed out the air that does the insulating.
Why mohair is the warmest thing to put on a cold foot
Mohair — the fleece of the Angora goat — has a structure that does two jobs at once, and for cold feet that combination is hard to beat.
- It insulates by trapping air, which your own body heat then warms — a proper thermal layer rather than a thicker one
- It moves moisture away from the skin, so you get warm feet rather than damp ones (see tip three)
- It keeps insulating when damp, unlike cotton, which gives up entirely
- It's naturally odour-resistant, so a thick winter sock stays pleasant for several wears
- It's tough and it's ours - knitted in Leicester, dyed in Leeds, and worn by us on Northumberland hills in weather we'd rather not describe
If you'd like the fuller comparison, we've set mohair against the alternatives in mohair vs cashmere vs merino.
Cold feet: your questions answered
Why are my feet always cold, even indoors?
Usually circulation. Your feet are furthest from your heart, so they're first to lose out when blood flow drops - which happens naturally when you're sitting still, when you're cold elsewhere, or as you get older. Movement helps, and so does a sock with no elastic squeezing the top of your calf. If it's persistent and one-sided, or comes with numbness or colour changes, see your GP rather than reaching for thicker socks.
What are the warmest socks for cold feet?
A thick mohair sock with a terry towelling loop - that's our Derbyshire. The loops trap air, your foot warms the air, and the air insulates. For indoors, Bed Socks are warmer still because there's no shoe compressing them.
Does wearing two pairs of socks keep your feet warmer?
Only if there's room. Two pairs in a boot that's already snug will compress the air out and restrict circulation, leaving you colder than one good sock would. If you do layer, use a thin base like Surrey underneath rather than two thick socks.
Are wool socks or mohair socks warmer?
Mohair insulates comparably to wool while wicking moisture better and drying faster — and dryness is half the battle with cold feet. It's also less prone to matting, so it holds its loft and its warmth for longer.
Should you wear socks in bed?
If your feet are cold, yes - warm feet help you drop off. The one rule is no tight elastic, which is exactly why bed socks are made without it.
How do I stop getting chilblains?
Keep your feet warm and dry, and warm them up gradually rather than sticking them on a radiator - sudden reheating is what tends to set chilblains off. The NHS page on chilblains has the medical detail.
Can the right socks help with a health condition?
Comfort, yes - a non-restrictive sock is kinder if you have swelling or sensitive feet. But socks aren't treatment. We've written about the practical side in health conditions and why people choose mohair, and if something's genuinely worrying you, please speak to your GP first.
