The Journey

We Understand How You Feel.
That’s Why We Created The RollerFoot.
The RollerFoot Story

The Injury

A few years back, I was playing tennis. We were about 20 minutes into a fast game when suddenly I felt something hit me on the back of my foot from behind. All of us heard a clear popping sound. I thought someone threw a racket at me and it hit me in the foot.

Momentarily I realized what had happened. I couldn’t take a step anymore, and as I examined my left leg around the Achilles, I felt a soft tissue, like nothing was there. Then I knew I ruptured my Achilles tendon!

The pain wasn’t too bad, but the inability to walk normally was terrifying. Here I was: couldn’t walk, and everything must stop: work and all you have to do around the house.


After a few days, my Achilles tendon repair surgery was done at one of the best clinics in Wisconsin. I woke up after the anesthesia with a cast on my leg. They rolled me out, handed a pair of crutches, and sent me home to heal.

The prospects were: no weight bearing at all on the injured foot for the next 4 to 6 weeks; after that, gradually increase the load for another 3 to 4 weeks, then rehab for a few months, and possibly full return to activities and sports in about nine months to one year.

That was a big bummer and a huge change of pace in my life.


My new life as a handicapped person had begun. I was stumbling around the house, learning the new task of hauling my body on crutches. I quickly realized that it was a very tough kind of sport.

Although physically I was in good shape, it was a losing proposition trying to do things on crutches. My hands quickly became sore; the muscles in my good leg were dead tired. But the bad-ass kicker in the pants was that pendulum-like motion of the injured leg down there, as the blood rushed down to the injury zone, causing additional sharp pain.

Standing on one leg without crutches trying to do something with both hands for more than 1 minute was almost impossible.

You sit at the kitchen table, and you realize that you can’t take this dirty plate to the sink a few feet away on crutches!

That was too much for me. I thought to myself, I wasn’t totally incapacitated – only one foot, but I couldn’t do such a simple task. There must be a better way in the 21st century!

The Birth of the Idea

So I began to look for solutions to free up my hands while remaining non-weight-bearing on one foot. I noticed that the kitchen chair was about the right height so I could place my knee of the injured leg on it and transfer some weight on that knee. That was very helpful! Now I could stand on both legs without putting weight on the injured foot and use both my hands!
The next step was right there – I realized that something like this chair could be tied to my bent knee, and it should roll around like a big skate!

Thus the idea was born! I began to draw sketches; I saw this new thing as having a nice modern shape, pleasant to look at, and, most importantly – very functional for the modern urban environment.

Making a Dream into Reality

My engineering background helped me to develop this idea into drawings and a lot of prototypes. I made many of them, small and large, out of sculpting dough, foam, wood, and other things, even using a hockey shin guard for a leg pad.

It took me many years of trials and failures, with the help and advice from people much smarter than I, before the first working model was launched and patented.

Today, we are making the new generation of RollerFoot out of advanced materials in an industrial setting in large quantities and with total quality control. RollerFoot has since helped to greatly improve the quality of life for hundreds of people, of which I am so proud.
