“Masai Barefoot Technology”, or MBT, is the first physiological footwear - that is footwear that has a positive effect on the whole body. The health and fitness enhancing concept being MBT is based on a simple insight: the human musculo-skeletal system is designed for walking barefoot on soft, natural ground. But we all spend most of our time moving on hard, flat surfaces. Mary is the only local person qualified to supply MBT footwear.
