WHY YOU'LL LOVE THEM

Soft, breathable and consciously made, these knee-high socks are designed to sit neatly just below the knee, creating a clean, confident silhouette.

A firmer fit through the leg gives structure and shape, while considered details — from seamless toes to reinforced heels — ensure they feel refined and well made.

  • Bespoke yarns that are luxuriously soft

  • Smooth, seamless toe for a polished, irritation-free fit

  • Reinforced heel and toe for long-lasting wear

  • Structured knee-high leg for a secure, supportive fit, best suited to slimmer calves.

At Teddy Locks, we have developed our own bespoke yarns to be:

Luxuriously soft
Smooth, refined yarns that feel gentle against the skin and remain soft, even with repeated wear and washing.

Breathable
Our fibre blends allow air to move naturally, helping heat and moisture escape, so your socks feel fresh throughout the day.

Durable
Built for strength and resilience, our products retain their shape and quality after regular use.

Quick-drying
Teddy Locks yarns release moisture efficiently, allowing your socks to dry quickly after washing.

Thermo-regulating
Our blends help maintain a balanced temperature, helping you feel comfortable when it’s warm and cosier when it’s cool.

Moisture-wicking
The fibers help move moisture through the fabric to support performance during activity and everyday wear.

Anti-bacterial
Our blends naturally help reduce the build-up of odour-causing bacteria, keeping materials fresher between washes.

Thoughtful design that elevates an everyday essential into socks that are comfortable, durable and made to perform.

Seamless toe
A smooth finish across the top of the toe to help reduce rubbing and irritation.

Reinforced heel and toe
Extra strength in high-wear areas improves durability and helps extend the life of each pair.

Engineered welts
Carefully constructed stitching helps socks stay in place without feeling restrictive.

Elasticated arch support
A gentle, supportive band around the arch that helps keep the sock securely in place and complements performance during sport and movement.

Arch support features in all Trainer, Quarter & Ribbed Crew sock styles.

Designed for the planet. Made for you.

I spent 404 days developing Teddy Locks - creating bespoke yarns made from recycled plastic bottles, upcycled textiles and natural tree-based fibres - engineered for softness, durability and everyday comfort.

All Teddy Locks socks are designed here in the UK, and within a tightly managed supply chain of under 250 miles, the bottles are transformed into yarn, knitted and finished by family-run businesses in North Carolina.

Teddy Locks was founded with high environmental and ethical standards set from the very beginning. You can read my story here.

Designed to be worn often and replaced less.

Shipped in 100% recycled and recyclable paper packaging.

FINALLY! Eco friendly socks!!!

These are great socks! The colors are pretty, and easy to find in the sock drawer! They are soooo soft and feel very comfy on. There is firmness to the wear but nothing restrictive. The extra material makes them "slouchy" very cozy but I can pull them all the up if I wish and they will stay put. Love that these socks are sustainable and long lasting. Highly recommend these socks!

Gave them to my husband and 15-year old for Christmas. They have enjoyed them. They must be comfortably soft otherwise the 15-year old would have nothing to do with them.

The socks I ordered from Teddy Locks are great! They are super comfortable and have held up after many washes. They are soft and stylish and fit well. It's also great to know they are helping the environment.

The Best Socks Ever

I love cool socks and the notion that buying these socks in particular would help out the environment made them that much more appealing. Then, I received my order and actually got to wear these amazing socks. These socks are the most comfortable socks I have ever owned. Overall, I would highly recommend these socks for anyone who is looking for cute, dress socks. The positive environmental impact is just the icing on the cake.
