Yes. Wool is one of the best fibres for keeping feet warm because its crimped structure traps air, and air is what actually does the insulating. With wool making up half of this blend, these are a noticeably warmer choice than a standard cotton sock for cold commutes, dog walks and unheated offices.

As general guidance for wool blends, a cool wash on a gentle or wool cycle is kindest, and drying flat rather than on a hot radiator helps the knit keep its shape. Always follow the care label on the pair you receive, since it takes precedence over any general advice.

This is a blend rather than pure wool, and the 20% cotton content softens the feel against the skin compared with a coarse all-wool sock. Wool sensitivity does vary from person to person, so if you know you react to wool against bare skin it is worth bearing in mind.

A single pair at £18 makes sense if you want to try the fit first. The three pair pack at £40 is the best value, working out at roughly £13.33 a pair, and it lets you mix darker colours for work with a lighter shade for weekends.

Yes. Crew length sits above the ankle, which is exactly where you want it with boots because the cuff protects your leg from the boot collar rubbing. They work equally well with trainers and everyday shoes in colder months.

Wool handles moisture better than most fibres because it absorbs damp away from the skin while still feeling dry, which is why walkers and hikers favour it. The cotton in this blend adds breathability on milder days.

Six: Navy Blue, Grey, Brown, White, Black and Light Brown. Black, Navy Blue and Grey are the safe choices for work and smart trousers, while Brown and Light Brown suit chinos, cords and boots.
