These are knee-high compression socks (compression stockings) that can be worn alone for a cool and easy feel, or layered when it's cold or you're concerned about UV rays, making them useful all year round. They provide graduated compression to comfortably tighten your legs, supporting the flow of lymph and blood that can cause fatigue and swelling, helping to move them upwards. They are useful for those who stand or sit for long periods, during travel, or when you're concerned about cold calves. They are also said to be beneficial for improving nighttime urination frequency. Leaving swelling untreated can lead to thicker legs and a loss of ankle definition, so regular compression care is essential for prevention and for creating beautiful legs. ***The fabric is a smooth, stretchy, and soft zo-ki type. ***This eliminates the worry of wrinkles forming around the ankle, which can be common with stiff compression socks. ***How to wear*** 1. Worn alone, they provide gentle compression support. 2. When layered, they offer firm compression! They work to combat swelling and fatigue, resulting in slimmer legs. Layering is recommended when you want strong compression, or when you are concerned about cold or UV rays. Layering these over skin-tone correcting compression stockings is also recommended. ***Country of Origin: Japan ***Made with run-resistant material. ****Knee-high length.
