The first time I put them on, I felt like I was walking on a spring. It’s a great feeling, a sort of seesaw motion!

I used to be a television technician, and I developed knee problems. Any new shoes that came out… there is nothing I haven’t tried. For the first time there is something which truly solved my problem. My father who is 76 could hardly walk, and today he walks freely and enjoys the shoes. He doesn't take them off, even on the Sabath. I intend to buy the entire collection.

Some people might say that the shoes are too expensive. But that really isn’t true. Considering how long they last, I must say I think they are extremely good value and the benefits they bring are priceless.
