You want shoes that fit your foot comfortably without slipping, and bend. It's a huge oversimplification, but you want to be using the front of the foot for control and traction, as per my shoddy 10 second diagram.
Maximise traction by striking the wall with a good surface area, compromising the direction of the force between the wall normal and the optimum jump trajectory, and regulating the length of the impulse using all joints.
i understand what you mean about parkour not looknig too good, but the crowd around my area WANT to see looking good - we explain but they still do - but im telented at them so i dotn see why i should put it to one side
