I am carried back 4 times

I already had four operations on the spine and it is the only brand of shoes that allows me to walk almost normally and give the impression of being normal.
It's true that at the beginning if we put them, one can have any evil in the back, but I assure you, it is only in the muscles and this is a sign that postural muscles work.
If someone does not convince of the benefits of these shoes, it is important not he buys them, to me personally, they changed my life.
I offered these shoes all my friends carried or with back problems and I changed their lives.
I work in the medical field and I confirm, you need a soft heel to absorb shock from walking to relieve the spine.
