I still bought them, convinced myself that I'd give them a decent try and at least wear them on the awful hot beach or something if they suck completely.
I love them. I only wear regular shoes now on rare occasions. The first two days were a constant source of laughter and I tried to walk on every type of ground (and - stuff) I could find. Childish? Hell yes, but fun!
Now they are comfortable like no pair of shoes that I owned before. While having no proof I do believe that I walk more straight with them and you relearn to roll your foot instead of stomping around.
If anyone wants to try this experiment and thinks about shoes like this: Don't give up after 5 minutes in the shop..
