I can't directly comment on these particular shoes because I didn't try them but what I read here reminds me of the pair shox running shoes I got a while ago. Heavy and stiff. I purchased them because I was curious about the shox system but didn't wear them much.
On the other hand I'm very happy with my latest pair of shoes: Nike Huarache Bball. Light (like half the weight of the shoxs) and comfortable.
Just a pitty I can't play at the moment.
