Socks are the cheapest part of your work kit and among the most important. The right pair keeps feet dry, cuts friction and fills the boot properly. The wrong pair can cause blisters, cold feet and odour in even the best boots.
Key points
- Choose merino wool or synthetic blends. Avoid 100% cotton.
- Socks should always be taller than your boot collar.
- Match cushioning to your boot fit and the season.
- Try boots on in the socks you’ll wear with them.
Materials
Merino wool
Merino is fine, soft wool that doesn’t itch like traditional wool. It absorbs moisture into the fibre and releases it slowly, stays warm when damp, and resists odour well. It’s the best all-round choice for most work boots in most seasons. Most work socks blend merino with nylon for durability and a little elastane for fit.
Synthetic (nylon, polyester, olefin, acrylic)
Synthetics dry fast, are very durable and usually cost less. They wick sweat away from the skin but hold odour more than wool. They’re a good choice for hot conditions and high-sweat work.
Cotton
Cotton absorbs sweat and holds it against your skin. Wet cotton increases friction, which raises the risk of blisters, and loses its warmth. Avoid it for long shifts in boots.
Height
A sock should always extend above the top of your boot so leather never rubs bare skin.
- Crew (mid-calf): for work shoes and 6-inch boots
- Boot height: for 8-inch boots
- Over-the-calf: for 10-inch and taller boots, loggers and pull-ons

Our top picks
Cushioning
- Light or liner: thin and cool. Good for warm weather or snug boots.
- Medium: padding at the heel and ball. The best default for most work.
- Heavy: fully cushioned. Good for cold weather and hard floors, but takes up space.
Cushioning changes fit. A heavy sock can take up close to half a size, so a boot that fits in summer socks may feel tight in winter ones. Many people keep a lighter pair for summer and a heavier pair for winter, and fit their boots in the heavier sock.
Features worth looking for
- Reinforced heel and toe for durability
- Arch band to stop the sock slipping and bunching
- Flat or hand-linked toe seam to prevent rubbing
- Shin padding for tall boots and pull-ons
- Mesh venting on top of the foot for hot environments
Sock habits that help
- Change socks at lunch on hot or wet days.
- Carry a spare pair in your truck or locker.
- Replace socks when the heel thins or the elastic goes. Thin spots cause blisters.
- Wash inside out and air-dry to keep wool soft.
If you get blisters even with good socks, see how to prevent blisters in new boots. If your feet still ache at the end of the day, read how to prevent foot pain from standing all day.

Are cotton socks bad for work boots?
Cotton absorbs sweat and holds it against your skin, which increases friction and blister risk and keeps feet cold in winter. Merino wool or synthetic blends manage moisture much better.
Should socks be taller than my boots?
Yes. Socks should extend above the boot collar so the leather never rubs bare skin. For 6-inch boots, crew socks work; for 8-inch or taller boots, choose boot or over-the-calf socks.
Do thick socks make boots fit tighter?
Yes. A heavy cushioned sock can take up close to half a size. Always try boots on with the socks you will wear at work.
