Nothing interrupts a cosy winter evening by the fire, a quiet Cornish coastal walk, or a
leisurely breakfast, quite like cold toes.

Our thick-ribbed silk blend socks bring warmth, softness, and a touch of luxury to everyday rituals — whether worn as indulgent bed socks or tucked into walking boots, wellies, or ski boots.

Knitted from a sustainable blend of recycled silk, lambswool, viscose, and nylon, they offer
natural warmth, breathability, and durability.

These beautifully thick socks are built to last - crafted in small batches from ethically sourced, Italian-spun yarn, a welcome alternative to flimsy synthetics that quickly wear thin.

Our Craft

Designed in our East London studio by Catherine Tough, a Royal College of Art graduate, and made with care in Portugal.  Every pair is crafted in small batches from ethically sourced, Italian-spun recycled yarn — because beautiful things should also do good.

Ethically sourced, recycled yarn
Fairly made in Portugal
Designed in Hackney, East London

Customer Reviews

Overall rating: 4.9 / 5 from 3786 reviews.

I really love Catherine Tough’s products - they are stylish, comfortable and well made. It is always a pleasure to buy from an independent manufacturer, but one whose small size doesn’t mean a compromise in terms of service and efficiency.

Unisex Recycled Silk Blend Chunky Socks - Grey & Yellow

I had a pair of your slippers as a Christmas gift 5 years ago. I LOVED them! I have worn them to death (they are still very serviceable, but I have worn the fur lining in places). I HAD to get another pair. My only criticism is that you don't add any kind of label to your slippers. It took me a lot of searching to find who had made them (the person who gave them couldn't remember). So, the best slippers I have ever owned by a country mile. But add a maker's tag!

Rust & Pink Spot Lambswool & Sheepskin Slippers

Dusky pink cashmere socks - soft, warm and so comfortable. They are the prettiest colour and feel so good on my feet. Will definitely buy in other colours!

Dusky Pink & Jade Cashmere Blend Slouch Socks

Bright modern colours. Very soft and comfortable, and warm. Washed once on a wool wash and came out perfect. My tip: if you have long toenails, pull the sock generously over them, to avoid holes appearing!

OUR STORY..

Designed by Catherine.
Made to last a lifetime.

Catherine Tough has designed subtly colourful, playfully patterned knitwear from her London studio since the early 2000s. Every sock, scarf, or gift idea begins with a sketch - a love of colour, a study of pattern and proportion, a belief that the things we use every day should be worth reaching for.

These aren't products you throw away after a season.  They're knitted from the highest quality natural fibres, designed with care, and made to become old favourites.  Our customers tell us the same thing again and again: 'I bought them as a gift and ended up buying more for myself.'

Read Catherine's story

How your socks are made

Every pair follows the same careful process - designed in Britain, made with integrity

01
Designed in London

Catherine designs each collection in her East London studio, inspired by the pattern and chaos of urban living, blending this with an old-fashioned sense of whimsy and a unique colour palette to create charming, individual products.

02
Natural fibres sourced

Each collection starts with the joy of a new shade card.  We use the finest natural fibres - organic cotton, Italian-spun lambswool, soft cashmere blends and eco-recycled silk, selected for softness, durability and the way they age.

03
Knitted with care

All our socks are knitted in Portugal; we regularly visit our makers to work on new developments and quality control …who doesn't love sunshine and a fresh pastel de nata?

04
Ready to love

We check and pack every pair of socks at our studio so they are ready to wear or give.  They only get softer with every wash and become your top-of-the-sock-drawer favourites.

Our Four fibres

We knit in cotton, lambswool, recycled silk & cashmere blends. Here's how to choose - by season, by feel, or by gift.

YEAR-ROUND
