i have the fit flop fit flops, boots and those trainers, i don't believe the toning claims but they are very comfy...i wear the trainers the least amount because they remind me of bowling shoes, they are wide not slim like the converse style i love. i have them in black. Perhaps i should ebay them.
I also have the reebok easy tone trainers, look nice if you do the sporty look, i quite often wear them with leggings, very comfy but i do find my legs ache the next day, maybe thats them working, perhaps i should wear them more.
