Ultra Flex Calf Stretcher™, the most Powerful way to Stretch calf muscles! 

This feet rocker is a remarkable invention for those people suffering from severe calf muscle stiffness. 

Ultra Flex Calf Stretcher™ holds the foot in proper position to stretch and strengthen the muscles, ligaments and tendons of the foot and lower leg. Increases flexibility and strength to help prevent and treat injuries. 

Stretching calf muscles is also the most important step in relieving any feet or heel pain! 

Stretching calf muscles is easy with lots of benefits. Calf flexibility can improve sport and athletic performance. That's why calf stretch has always been an essential part of training warm up. 

Calf muscle can prevent injuries. Healthy calf muscle length encourages ankle and intrinsic foot muscles to actively stabilize your own ankles while you run and jump. You are less likely to sprain your ankles or strain your Achilles' tendons. 

If you suffer from painful conditions such as: plantar fasciitis, Achilles tendonitis, overpronated feet, reccurring bunions, Shin splint or Muscle cramp (Muscle cramps in the calf are a common complaint for those who exercise frequently). You should consistently stretch your calf muscles daily to achieve fast recovery and pain relief. 

What is a foot rocker and how does it help? 

Normal exercises that help are usually done against a wall or on the edge of a step, but using the rocker allows you to flex that little bit more. 

The foot rocker is designed to help you stretch by allowing your foot a greater degree of motion, therefore making the stretch more effective. 

You might not think that this would make much difference, but many people have praised the effectiveness of the foot rocker. 

How to use the foot rocker? 

  • Find somewhere sensible to use the rocker and somewhere that you can hold on to something to help you balance.
  • Step on to the rocker with 1 foot and stand upright (you can let the other leg hang or place it onto a higher platform).
  • Begin to roll forwards and backwards slowly on the rocker, trying to keep your weight over the top at all times.
  • Keep your knee straight to stretch the gastroc muscle and knee bent to stretch the soleus muscle.
  • Hold the stretch for at least 30 seconds 

How does it help plantar fasciitis? 

As part of the exercises and also due to the angle and position of your foot, the stretching will help pull on the Achilles tendon and also on the plantar fasciitis tendon on the bottom of your foot. 

Over time, this increase in flexibility will help reduce pain and the bad effects of PF. 

Great for intermittent heel pain! 

For those of us who are not regular exercisers and suffer from the odd bout of heel pain that appears to have no specific cause, using a device like this will help. 

If you can commit to doing these exercises once per day, or when your heel pain starts to trouble you, the stretching will help loosen up those tissues, muscles, and tendons around the calf, ankle and foot. 

This will help keep your muscles loose and will help reduce any tension pulling on your heels.
