Devices to stretch your calves vary from easily transported, rolling objects to fixed items. You'll most often see these devices in a gym setting or a physical or sports therapy practice. Some of devices are expensive, but many are cheap, easy to find and just as effective. The key is to find a device that releases both the gastrocnemius as well as the soleus and Achilles tendon. Make sure any device can be used to release all three of these key muscles and tendons in the calf, as tight calves are the bane of many runners and athletes alike and the source of many athletic injuries.
Slant Board
A slant board is a simple device that is often found at gyms. It can be part of an overall piece of stretching equipment, or a single piece that takes up a small corner. The device is simple, a platform with gripping material to prevent sliding set at a slant. Often, the slant can be increased or decreased, though many are set at one, permanent angle.
Using a slant board is simple. Step onto the board with your feet facing forward. This stretch will focus on your gastrocnemius muscle. Bend your knees slightly to stretch your soleus muscle and Achilles tendon.
Roller
Rollers come in a variety of forms. The most sophisticated looks like 270 degrees of a circle with platforms at both ends of the circle. The least sophisticated is a can of soup.
Using the more sophisticated type, you step on the roller with a support, such as a chair or railing. Roll through a variety of static stretches, angling each to ensure a full stretch of the calf. Using a can, you can step on the can to roll your feet back, engaging both the Achilles and soleus as well as the gastrocnemius.
Step or Block
The least expensive option is a simple step or wooden block. Failing either of these, a strong, thick book is an effective device. The idea is to step onto this raised step or block and drop your heels off. Holding the stretch with your knees straight provides a deep stretch of the gastrocnemius. If you bend your knees, you stretch both the Achilles and the soleus.
