Calf Pain

RapidForce V Shape - Muscle Support & Pain Relief System

RapidForce® Shapes stabilize and support the muscles, tendons, and ligaments in the calves. The V Shape is designed to reduce swelling by gently lifting the skin above the pain point, which can help circulate blood, oxygen, fluids, and nutrients to an injury site.

Often a consequence of overuse or under-conditioning, calf pain can range from nighttime cramps or charley horses” to a stabbing sensation to a deep, dull ache within the muscles. The pain can be described as cramping, stabbing, aching, tenderness, a sudden sharp pain, or general soreness. The calf itself may appear inflamed, swollen, or, in more severe cases, bruised.
Calf pain is common in athletes who are dehydrated, have torn or strained a calf muscle, run on hard or uneven surfaces, or did not adequately stretch before activity. Pain in the calf can also strike people who have poor form when landing after jumping or hopping, but it can also be a byproduct of other conditions or injuries, such as Achilles tendonitis.
The V Shape is designed to help reduce muscle pain and is an especially effective treatment for calf pain. The V Shape’s central core is placed atop the pain point, which stabilizes the injury site, and its dual arms are stretched outwards, providing structural support for the muscle, tendons, and ligaments surrounding the calf muscles. The Shape is also designed to provide mechanical lift, which means the upper layers of the skin are literally lifted, which creates more subcutaneous space for the blood to flow and oxygen, nutrients, and fluids to reach the injury more efficiently.
RapidForce® Shapes are unlike any other pain-relief product on the market today. Each Shape’s  patented design was carefully developed and perfected by a team of physical therapists, athletic trainers, engineers, and an ultrasound technician who sought to create a product that supports the muscles and helps relieve pain caused by muscle, tendon, joint, and ligament injuries. RapidForce® Shapes are used by athletes at all levels, including professional athletes, semi-pro athletes, and people who lead or want to lead an active lifestyle.

Time it Right

While RapidForce® Shapes can be applied at any time, they should be applied 1–2 hours before beginning strenuous physical activity. The Shapes can start working is as little as two hours, but some applications take up to four hours.

Prep Skin Thoroughly

Wash and dry the skin to remove oils, moisture, and dirt. Trim or shave body hair; this helps create a more secure bond and more comfortable removal. Apply the provided Skin Tac liquid adhesive wipe. Allow 30 seconds for it to dry.

Customize Stretch

Secure the Shape’s central core to the most painful spot. For daily wear or moderate-to-light athletics, a mild stretch of 1/2” is ideal. Application instructions vary based on Shape, so read and follow the instructions mailed with your shape(s).

Secure Bond

With both the Shape and the skin at room temperature, carefully begin applying the shape. Once the shape is secure, rub it vigorously to maximize adhesive bond to skin.

    You may begin feeling relief within a few hours. However, it could take up to 24 hours. RapidForce shapes can provide pain relief and muscle support for up to five days but can be removed at any time. To remove, pull from the end of the arms to the center. If hair is present, pull in the direction of the hair’s growth to reduce discomfort. For easier removal, use mild warm water in the shower and then remove the shape slowly.
