In recent years there's been a growth in awareness of so-called "coach class syndrome" - the tabloid name for potentially fatal deep vein thrombosis. DVT is caused when your blood clots - typically in your legs - and then if the clot moves to your heart or lungs it can kill you. I know because I've had one. But it isn't just caused by long-haul flights, or being seated in coach. Any circumstance whereby you're standing or sitting for a prolonged period can be just as deadly - even if it's just your desk at work.
Falke's Leg Energizer products (from the Leg Aesthetics collection) are designed to specifically minimise those risks. They work be offering serious compression - helping your veins and arteries to work effectively - and help keep the blood flowing. There are other benefits too, of course - your legs feel lighter and more energetic, and being Falke the quality is unsurpassed. They look amazing and should prove durable too.
So while the 41785 Leg Energizer 50 denier knee highs may look expensive, believe me, they're worth every penny. Even supermarkets now sell so-called "flight socks". But if you're serious about minimising risks these come highly recommended.
