i have been doing alot of running lately and have been having alot of problems with shin splints. I went to a pediatrist and he gave me an orthotic to wear which is really hard and after that i started running with it in my shoe. It relieved my shin splints but now the bottom of my foot is bruising because it rubs against this hard surface when i run. I went back to the pediatrist and he said the insert is supposed to be hard because i am flat footed. The other day i am at foot locker and the foot locker lady tells me i should run with a soft insole but i am afraid my shin splints will come back if i use a soft insole. What should i do about this? Another thing i notice is there is alot of space in front of my shoe should my shoe have space in the front or should my foot be right up against the end?
