Has anyone tried Gravity Defyer brand shoes?

I need all the help I can get in walking long distances. These shoes seem to have a little spring in the heel of the shoe. Anyone tried them?

I think they are too light for a 800 km walk. They might do for a day or two walks without a heavy pack, on asphalt.
They do seem good walking shoes, will they last the whole Camino? rain, mud, rocks and stones, a lot of sweat, stress.
But- i have seen people walking the camino with Crocks and 5 $ shoes bought at a cheap store.
I myself don't like taking chances and being stuck on a Sunday in Spain with no shoes store insight with damaged shoes.
