Achilles Tendonitis

Final position of I Shape for Achilles Tendonitis pain

RapidForce Shapes are uniquely designed to provide pain relief and dynamic mechanical support to the muscles, ligaments and tendons of the leg.

Achilles tendonitis is often described as a sudden “pop” in the ankle, heel, or lower leg that results in muscle stiffness, enlargement or swelling of the tendon, bone spurs, constant and worsening pain, pain in the tendon itself, or severe pain along the vertical back portion of the lower heel. Individuals describe the sensation of a damaged Achilles tendon as stiff, warm, burning, mild friction, or an ache in the back of the leg or heel immediately after activity.

The RapidForce I Shape is designed to reduce Achilles tendon pain as well as a variety of foot and ankle pains. The I Shape is place and stretched upwards over the Achilles tendon, creating dynamic structural support.

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 optimal performance, stretch the arms minimum 1". 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.

  1. 1. Anchor the end of the I Shape

    1. Anchor the end of the I Shape

    Peel off the backing of one end of the I Shape and secure to the bottom of heel. Press to secure the bond.

  2. 1. Anchor the end of the I Shape

    2. Apply remainder of I Shape - 1" Stretch

    Peel off the backing of the larger portion of the I Shape, leaving the opposite end tab in place. Point the foot slightly downward and stabilize the end tab on the heel with one hand. Customize the stretch for level of activity and pull upward toward the calf. (1" is ideal; do not pull taut.) Smooth the fabric onto the skin, moving from the end tab upwards.

  3. 3. Secure end tab

    Remove the backing from the last end tab and place on the skin; do not stretch this small piece. Press over the entire I Shape for about 10 seconds to secure bond.

    4. Feel Relief and Remove

    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.
