Most people are unaware of the effect their feet can have on their overall posture. When you have foot posture problems, your body does not move the way it’s supposed to, and will compensate with a series of movements. Thereby increasing stress on your ankles, knees, hips and lower back. This affects the alignment of your posture.

MASS4D is engineered to provide corrective support during wear. This support helps to correct the alignment and regulate improper movements. Proper support brings increased balance and stability to the body. We treat your feet as the foundation for your whole musculo-skeletal system.
