Need support that will endure your toughest workout? KT Tape Pro® is here for you. It has been designed to relieve pain and provide support where you need it, staying in place through multiple workouts. * KT Tape Pro® was created with performance in mind, to work in the harshest environments. It is the world's first 100% synthetic kinesiology tape, re-engineered with stronger adhesive, to outlast anything you can throw at it.KT Tape Pro® can be worn in the shower, in the pool, or while riding waves at the beach. Synthetic performance fibers are fast-drying, water resistant, and provide superior strength, stretch, and recoil. KT Tape Pro® also features an adhesive formulated to remain in place for 4-7 days.KT Tape Pro® fibers feature a stronger elastic core which delivers better support for muscles, joints and tendons without restricting comfort and range of motion. This improved elastic core retains its elasticity far better over time and provides more durable support than cotton kinesiology tape, lasting as long as you need it. Like top athletes, it relies on both strength and endurance to get the job done.KT Tape Pro® is pre-cut and ready to apply right out of the box. Pre-cut strips have rounded corners which help to prevent the corners from catching on clothing or the edges fraying. Each roll contains 20 pre-cut strips that are 10 inches long and 2 inches wide.KT Tape® products are Hypoallergenic, Latex-Free, Natural Rubber-Free! This means that our products have been designed and developed to contain fewer potential substances that can trigger allergic reactions. While our goal is to provide you products that won't cause any irritations, if you are known to have sensitive skin or prone to irritation, we recommend testing a small piece of KT Tape applied with no stretch on tougher skin such as the knee or forearm before utilizing our product line.
