The Swiss MBT company refers to their products as the "anti-shoe". The basic idea of MBT as footwear comes from the significance of MBT. MBT stands for "Masai Barefoot Technology." A how-to commercial states that MBT is a 1400 year old Masai Technology. Of course the Masai refers to the ethnic group found in Kenya and Northern Tanzania. The footwear itself emulates walking on an uneven surface. As a result, it allows each person who wears MBT to walk as the Masai do. The first step is on the heel sensor, then the foot rolls forward and then an upward push. These shoes are not recommended for running, although the same motion is used by Masai/Kenyan runners who have won many marathons.
It is interesting because these shoes should improve one's posture among other health benefits. The MBT website lists more benefits here.

I look forward to having a pair to see for myself.... I am prepared for the initial "getting used to" since this footwear requires a learning curve to use. One effect could be tiredness after the first 20 minutes or so. The instructional concludes by recommending to remove these shoes if you feel tired and that there will be a curve where one can wear these shoes for longer stretches of time.
The concept is good: using new technology to enable old technology in extremely developed parts of the world.
