Query: didn't really help

This book is very short and doesn't really have any good suggestions or solutions. I have flat feet and a lot of pain in my feet and lower legs (up to knees) because of it. This book tries to solve that problem with visualization techniques to get you to walk correctly and keep your ankle, calf bones and knees lined up correctly. But it didn't have any concrete steps one could take to minimize foot and knee pain. No exercises or recommendations on shoe inserts, etc. I wanted and expected more from it.
