Englin's Fine Footwear presents the Fanaka GTX from MBT. MBT, or Masai Barefoot Technology, was developed by the Swiss to emulate the natural walking conditions of the Masai. A semi-nomadic tribe from East Africa known for having excellent posture and almost never experiencing joint or back pain, the Masai have adapted their bodies by walking barefoot on the soft, sandy Mara plain, developing natural shock absorbers that protect their back, knee and hip joints.
