I am 76 years old, active, and healthy, but have had several almost falls when my Go Walk shoes grabbed a smooth floor I was walking on. Sunday it happened again in my dining room on wood floor over concrete and I fell HARD!! I hit my knee, hip, shoulder, elbow and right FACE! I spent yesterday in the ER getting X-rays and CT scans - luckily no bones broken, no brain bleeds, no orbital fracture. These shoes are DANGEROUS!!! User's recommendation: Do not purchase!
