ProStrech and ProStretch Plus Calf Stretchers: Are They Effective for Runners?

The Medi-Dyne Prostretch and Prostretch Plus are simple, but effective calf stretchers for runners. If you struggle with tight calf muscles, Achilles pain, or Plantar Fasciitis, calf stretchers, like the Medi-Dyne, are one of the most effective ways to relieve tight calf muscles.

Calf stretchers work extremely well. And, since they are cost-effective compared to more expensive tools like massage guns or getting a sports massage, I highly recommend them to every runner I coach. They are a must-have piece of equipment for every runner.

When combined with your normal flexibility routine, such as calf stretches, you can really improve your flexibility and reduce calf tightness. 

In this article, I’ll cover what calf stretchers are, how to use them, and the benefits. I’ll even show you some of the tools I use and recommend to my coaching clients.

Recommended Calf Stretchers

I personally own the Original ProStretch calf stretcher. Either are great options. The biggest difference is the plus can support more weight (up to 300lbs), and is adjustable. The original is just hard plastic and has fixed angles.

My Recommendation Based on What I Own
ProStretch the Original Calf Stretcher and Foot Rocker
  • Physician Trusted & APMA Accepted: The product is medically proven and widely used in physical therapy clinics, indicating its effectiveness and reliability.

What are the differences between the ProStretch and ProStretch Plus?

When comparing the ProStretch Original to the ProStretch Plus the primary differences are:

  1. Adjustability: The most notable difference is the adjustability feature. The ProStretch Plus offers an adjustable heel rest, allowing you to customize the degree of your stretch. This feature is especially beneficial if you require a more tailored stretching experience or are dealing with specific conditions that need targeted stretching. The Original version, on the other hand, does not offer this adjustability.
  2. Size and Weight Capacity: The ProStretch Plus is designed to accommodate larger shoe sizes (up to size 14) and supports a higher weight limit (up to 300 lbs). This makes it suitable if you have larger feet or a heavier build. In contrast, the Original version is designed for shoe sizes up to 12 and has a recommended weight limit of 250 lbs.

The Plus version offers more flexibility and customization in stretching, while the Original might be more straightforward and sufficient if your stretching needs are more general. I personally have the ProStretch Original and never have found it to limit me in any way.

Alternatives to the ProStretch

The Professional wooden slant board by StrongTek is another tool I highly recommend for those who struggle with plantar fasciitis, Achilles pain, shin splints, calf strains, and other injuries.

I recently added a slant board to my home workout equipment list as we used it during my physical therapy and my physical therapist recommended it as something every runner should own. Since getting mine, I agree.

It is a great option if you want a higher degree of stabilization, more options on the stretch angle, or you want to stretch both calf muscles at the same time. The slant board allows me to get a feeling of a deeper stretch and since it does not rock, it is a bit easier on my knees.

However, I use both the StrongTek slant board and MediDyne ProStretch calf stretcher. Using these tools helps me with stretching the Plantar Fasciitis AND the calf.

How to use the Medi-Dyne ProStretch or ProStretch Plus

Medi-Dyne Pro Stretch Calf Stretches For Runners

  1. Tip: Not shown, but I put my non-stretching foot on a small wooden box or step (to keep both feet level when starting the stretch) and then place the calf to be stretched in the ProStretch. Be sure to have something to hold on to in order to steady yourself.
  2. Placing all your weight on the side to be stretched, lift your toes while rolling back so your toes go up, and apply the stretch to your calf muscle.
  3. Hold for approximately 15-30 seconds and then relax. Be careful to not overstretch. You want to apply tension, not pain when stretching.
  4. Repeat for several repetitions of each calf muscle and as often as needed to increase flexibility. I recommend 2-3 times per day. (I actually keep it next to my bed as a constant reminder to use it.)

Final Thoughts

If you suffer from Plantar Fasciitis, Achilles pain, or various forms of tendonitis, then calf stretching with the Medi-Dyne ProStretch can be a great way to help alleviate the pain and start your rehab process.

To prevent or get rid of these issues, you will need to combine a combination of stretching, strength training and smart training.

And, if you do not have any issues currently, calf stretchers will help with overall flexibility and mobility.
