Certified Pedorthists ( Canada) are trained in the assessment, creation, modification and fir of footware and orthoses to help deal with pain, discomfort and disabilities in the legs and feet. Footwear can change a person's balance, improve his body's alignment, alter the way she stands or walks and protect against injury. For people with lower limb ailments, pedorthics can be the difference between being able to watch, and being able to do.
