You need 10 degrees.

Range of motion in the ankle joint shows up everyday. From walking the dog and picking up laundry, to competitive running or an afternoon surf sesh, we need at least 10 degrees of ankle dorsiflexion for healthy and pain free movement of our entire body.

Faster, more effective recovery. Unlike slow and ineffective stretching routines, Ankle Flex™ replicates manual therapy techniques to deliver measurable improvements.

Ankle Flex has been proven to restore functional ankle dorsiflexion, increase squat depth and improve function on stairs, ramps and flat walking in just 3 weeks of daily use.

Before & after using Ankle Flex

A 55 year old female that catastrophically broke her left ankle 10+ years ago which resulted in loss of almost all left ankle flexion—causing unstable gait, hip and spine pain, and making it extremely difficult for her to go up and down stairs. In the video on the left, taken in the motion capture laboratory before using Ankle Flex, you can see her difficulty on stairs and slow pace. 

Three weeks later, after using Ankle Flex daily, note her ease, pace and ability to trust her left leg and demonstrate normal gait on the way up and down the stairs.

“I was able to use Ankle Flex for three weeks, and the results were incredible! For the first time in ages I can run up a flight of stairs, I can squat and I can walk erect, and I don’t have a waddle. Ankle Flex has truly changed my life!”

—Anna

Tested and refined for over a decade, Ankle Flex can be used at home or at the gym, without assistance, allowing more frequent stretching without increased visits to physical therapy.

Ankle Flex’s patented technology has been developed by Physical Therapist Esther Smith, DPT, Cert. MDT, to allow deep stretching and mobilizing of the ankle joints and surrounding muscles to help increase ankle dorsiflexion.

We also provide supportive exercises that will help you move freely from the ground up.

"I broke my ankle twenty years ago, and since then I’ve had to get used to limitations in my ability to climb, hike, ski, and just walk up and down steep hills. I used Ankle Flex for three weeks, and I am amazed at how much movement I regained from using it about seven minutes a day. Nothing else has worked so well and so easily to help me regain movement I thought I’d lost forever."
