Ladies who lead busy lives & are on their feet all day usually need a light support tight to help their circulation & ease aches & pains in the legs. We don't always want to wear sheer support tights though & these tights from Kunert, at 40 denier, are semi opaque & add just that little something to our wardrobe. If we need to have support it's great to have a choice. Sheer or opaque, now you can decide! Quick word on Ginko: Ginkgo works by increasing blood flow to the brain & throughout the body's network of blood vessels that supply blood & oxygen to the organ systems. It increases metabolism efficiency, regulates neurotransmitters, & boosts oxygen levels in the brain, which uses 20% of the body's oxygen *NB Size 5 have a comfort gusset not cotton.
