So what is Rule #5? "It means 'Harden the %#$& up!' It's a shorthand my coach uses to motivate me during races and training when the conditions are tough and out of my control. It helps me adjust mentally and keep pushing no matter what."

A native Wisconsinite, decorated high school running athlete, four-time national champion at Notre Dame, and bronze medalist at the 2020 Tokyo Olympics in the marathon event, Molly's career is a testament to dedication and resilience. Molly is an American professional Runner who competes at an elite level in long-distance events, including marathon, half marathon, 10,000 meters, and other track & field events. She rose to prominence in 2020 when she placed 2nd at the US Olympic Marathon Trials, securing her spot on the US Team for the 2020 Tokyo Summer Olympics. There she won Bronze, the first American woman to win an Olympic medal in marathon since 2004. She is currently training for the Olympic Trials in 2024 to secure a spot in the Paris Games.

Molly's Rule #5 Tape is a collaboration between KT and Molly Seidel. This Limited Edition KT Tape is custom designed by Matt Shapiro and captures the intensity but also fun with which Molly approaches running.

Molly's Rule #5 Limited Edition Tape is a specially designed version of KT Tape Pro Extreme. The extra-strength adhesive within KT Tape Pro Extreme® is specially formulated to help with adhesion during strenuous activity through extreme conditions including wet conditions, high heat, high humidity, or oily skin. It has been designed to relieve pain and provide support where you need it, staying in place through multiple workouts. *

KT Tape Pro Extreme® can be worn through your run, 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 Extreme® also features an extra-strength adhesive that will remain in place for up to 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 Extreme® 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 with 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.
