Cushion arch supports provide instant compression and cushioned support for lasting comfort across the arch of your foot. This helps reduce the heel and arch pain caused from flat foot, plantar fasciitis and other foot problems. Also helps with your back pain caused from a poor posture. Durable, non-slip sole can be worn as long as comfortable. The cushion thickness of the arch support measures 10 mm without any pressure on it and 3 mm with your body weight on it. Directions to wear: It is designed to be worn with the green color fabric touching the bottom of your foot and the pointed side facing towards your heel. It should be positioned mid-foot around the arch area. However, everybody has different areas of their feet that need more support than others so rotate the arch supports a little to the left or the right AND move them back and forth depending on what feels most comfortable to you. Also, if the compression band feels tight and uncomfortable on wearing the first time please stretch the band a few times and then wear it. They can be worn on or under your socks. The cushion arch support will then conform to your feet and provide you the maximum comfort. Cleaning instructions: Hand wash with mild soap and water. Rinse it well and let it air dry. For longer product life DO NOT machine wash, tumble dry or dry clean. Package includes: 1 pair / 2 pcs JERN Cushion Arch Support for Flat and Achy Feet in a sealed polybag.
