When walking in MBTs, the ground is no longer flat and stable, so the body has to use more muscles to compensate and create stability. This activates the whole body, increases back muscle activity, improves posture, tightens buttocks and thighs and even burns more calories. All while reducing stress on the ankle, knee and hip joints. And with extensive scientific documentation to back up these claims, healthcare professionals around the world are now recommending MBT footwear in the treatment of backache, musculoskeletal injuries and other physical pains.
