Which part do you mean? The front, which I would take it that your describing as the 'toe', is the pedal! thinking the only way your fix it, is to replace the with a new pedal. There are some spares avaiable for Look Keo Max 2 pedals, but you need to look at the condition of the pedals and the cost of the spares, vs just replacing them with new pedals.
Really wondering what you have done to get the pedal out of shape, they have a composite body, which doesn't want to bend/go out of shape under normal use.
