I bought my fit flops when they first came out, they have toned my bum and thighs a bit but I only wear them around the house. I want a pair of the new Reebok ones that are in the shops now, they look much nicer.
I just bought the dark brown pair in the picture, cost £45 at Bentalls Kingston. They look like they have more support than the reeboks, and are quite comfy so I will persevere.
I wear flip flops all the time, but they are so thin and no support at all, as you can tell from my previous threads I am starting to get knee and heel problems, so think its time for some comfort. Well worth the money if it stops the pain in my joints.
