Travelling overseas? Consider wearing PHITEN Ti Compression socks. These socks utilise a graduated compression design to prevent swelling and discomfort during flying or from staying on the feet for long periods of time. Graduated compression is developed with 'higher compression fabric' on the upper calf and 'lower compression fabric' at the ankle, to gradually diminish pressure going upwards. Blood clots, also called deep vein thrombosis (DVT), can be a serious risk. Don't keep your legs crossed! Exercise as much as you can. Point your toes and move them around in a circle. Get up and stretch your legs as often as possible. Safe travels!
