.Allie is 5 years old, she slipped an fell walking on our new hard wood floors, when she was just 2 years old, she was needing surgery on both of her knees, but she could not have the surgery until she lost 8 lbs.. she was just to over weight to have the surgery, so we decided to tire these Boots, They worked!!!!! She could walk by her self. The Boots are straighting her legs/knees, so she can walk.  So she has been wearing this kind and brand from this company ever since. It has been three years now, this is the second pair we have bought from this company. Yours Truly. Rhonda Cones. 5-19-2017
