The shoe that is considered by many to be the anti shoe is the Masai Barefoot Technology (MBT) shoe the design of the shoe is supposed to mimic barefoot walking, so it is the shoe you wear when you are not wearing a shoe. It is supposed to increase muscle activity when walking to give a greater work out. The company even claimed that the MBT Shoes could be used to treat cellulite because of the extra muscle activity. This claim has been criticised and the company no longer make the claim on their website. The shoes are also helpful for a range of postural complaints in many people.
