TGN - the bunnyman is right!
I know I posted something on this recently when my son complained about foot ache in his 2S Pro skates earlier this year.
We went to the most qualified skate shop In Montreal and was told that his super feet where to rigid. I was shown how your arch reacts when you move your hips up and down in a static position and the arch goes up and down with your movement. His super feet where not allowing him to do so - I was all in for a custom set but was told but was told to look at the off the shelf Graf insoles. A pair was selected for him based on his arch type and length ( not sure if there where any other parameters taken into account ) - since he has them, no more complaint's!
