Sia Merino Knee High Grey Socks Navy


Crafted from incredibly soft and cosy merino wool paired with a zig-zag sparkle of navy lurex, the Sia knee-high socks add a stylish twist to your daily outfit. Wear them beneath jeans or skirts instead of tights to keep your legs warm during the colder months. The zig-zag design is created by an innovative new twist on traditional hand-intarsia processes, true to Genevieve’s slow fashion ethos.

Expertly twinning comfort and style, our Sia knee high sock is perfect for adding a little sparkle and maximum warmth to your day. The subtle sparkly zig-zag design offers an innovative new twist on the traditional hand intarsia process, while the premium construction – including ribbed trims and seamless toes – pairs a striking look with an irresistibly soft feel.

Made from soft – yet highly durable – machine washable merino wool in a grey melange, twinned with a zig zag sparkle of navy and silver lurex.

The sparkly yarn detail within our GS socks has FSC (Forest Stewardship Council) and Eco Vero certification.

Being certified by the FSC means that any products containing wood and its origins (in this case the cellulose used to produce viscose) comes only from forests managed in an environmentally responsible way. Likewise, EcoVero certifies the origin of the product is from green sources, and that an eco-friendly production process has taken place.

The complexity of the Sia’s innovative zig-zag stripe should not be overlooked. Creating this pattern is a highly complicated technique that not only challenges traditional intarsia machines, but – in true reflection of Genevieve’s slow fashion values – also takes a long time.

With the Sigi sock, Genevieve continues to demonstrate her dedication to sustainability and slow, considered fashion. Rather than sourcing her production overseas, she works closely with a long-standing, family-run mill based in Derbyshire who manufacture in small batches to help limit waste as much as possible. The signature intarsia design of the Sia is crafted using a traditional machine-led method coupled with a hand-finishing technique that truly embraces the joy and beauty of artisan craft.


For those who feel the cold and need ultimate warmth this season, let these subtle Sia knee high socks flash from underneath a pair of cropped leg trousers; providing a welcome dose of sparkle and cosiness on dreary rainy days.

I love my GS sweater: the wool has the perfect softness, the cut is great with everything, the colour is stunning.
I have been wearing it since I got it.
