Graduated Calf Compression — Ankle to Knee

Lift, every step.

Three zones of progressive compression, knit directly into the fabric. Higher at the ankle, gradually easing toward the knee — the proven pattern that supports venous return and helps reduce swelling.

Frequently Asked Questions

Answered. Plainly.

Are these medical compression socks?

They're engineered with graduated compression to support circulation and ease tired legs, using the same proven ankle-to-knee gradient pattern. They're designed for everyday wellness wear, not as a substitute for medical-grade therapy — if you have a clinical condition, please consult your doctor.

Will they help with leg swelling after long flights?

Yes. The graduated 24 → 14 hPA compression from ankle upward is exactly the pattern recommended for supporting venous return during long periods of sitting or standing, including air travel.

Can I wear them all day?

Yes. The seamless Italian Craftsmanship knit and breathable mesh structure are designed for all-day comfort. The functional yarns (Nano Silk, Tourmaline) help keep skin moisturised and odour-controlled.

Are they comfortable in hot, humid weather?

Yes. The mesh-knit ventilation and moisture-dissipating yarns are engineered for tropical conditions. They're a true everyday sock — not a thick medical garment.

What's the difference vs the Crew Socks?

The Contouring Socks are knee-length with graduated compression for circulation. The Crew Socks are ankle-height for everyday use and don't include the compression gradient — both share the Italian seamless knit and Japanese 4-in-1 yarn.

How do I wash and care for them?

Hand wash in cool water with mild detergent. Do not bleach, do not tumble dry. Lay flat to dry to preserve elasticity and compression strength.

How long do the compression properties last?

With proper care, the Italian Craftsmanship seamless construction is up to 60% stronger than standard knit fabric — the compression gradient holds through repeated wear and gentle washing.

How do I choose the right size?

Please refer to the Siltera size chart on this page when finalised. Compression socks should feel firm but not pinching — if between sizes, the larger size is recommended for all-day wear.
