Travel Compression Socks have been providing well thought out travelers over the past few decades. It is legal to reduce airborne pain on international flights. They have different compression strengths, 10-50 mmHg (millimeters of mercury). In most countries you can purchase any packing socks over the counter, which is 20 mmHg and below; Anything more than this amount requires a medical regulation.
Word to the Wise Men: Diabetics can not use compression socks because they greatly increase blood circulation in your legs and feet.
Travel compression socks show real value on long international flights and after you start using them you will never return. I recommend two or three pairs of packages for the next trip: one for flight, the other 3000 meters of altitude and the third for any strenuous activity that can cause a pain in your leg (eg hiking, cycling or jogging)
If you bought a non-prescription travel compaction sock you can wear them all day; If you received them from your doctor, ask them for their proper use. It is worth repeating that diabetics do not have to wear these socks. Many travelers also use compression socks when hiking, especially at high altitudes. It is safe to wear them during the day (if they are over the counter), and many enjoy them even if they do not travel.
All right, enough about health benefits, what's up with fashion? Do not sweat; Compression socks range from knee to ankle. Heck, they're still selling the socks for pantyhose!
