MBT stands for Masai Barefoot Technology, which was created in 1996 by Swiss engineers, focusing on the remarkable physical abilities and beautiful posture of the Maasai people who walk barefoot on the ground. The Maasai, representing East Africa, are known for their beautiful posture and outstanding athletic ability, without suffering from joint pain or back pain. This "secret of the Maasai" lies in "walking barefoot on the soft, uneven natural ground," which may seem simple, but requires maintaining balance throughout each step. This was the secret to their health. MBT shoes replicate the "natural instability" that the Maasai experience even on hard asphalt. They function as conditioning shoes by reducing the strain on the soles of the feet and promoting the activation of often neglected muscles throughout the body.
