Like from most reviews from customers, I'll say that this is not my first shoe. I couldn't stand more than half an hour because of my knees. Now I can watch a concert on my feet for over four hours. While I walk, I have almost no problem. bur until I get used to this shoe I had about three months of ache on my back of upper body. And fell twice seriously because of narrow steps of some stairways. If I had not an judo background I would be seriously wounded bur did not have a single injury . Now I learned how to handle. This shoe also saved me from a curvature of spine after a serious hit from my "defense line" boy, done by joke. You always walk on your fingers, bur you are very comfortable. you can not run, you must use normal shoe only for running but After 5-6 years of usage, I believe I will learn to run also. . if you leave to use few days, you bend to front and your balance is disturbed, your legs will ache bad. but if you want healthy legs in your advanced years, you must use it. But carefully for first two years. consider you learn to walk from the beginning.

Photo is 2016 dec.  Soft material in it desolved completely during this year, I kept using it. But just now top part left bottom part forever. :(

3 years life 1 year using with difficulty.

But Still I use other MBT and will continue to use. I never use chinese ones they don't fit and most probably rubish. Mine are vietnam fabric.
