Our system measures forces passing through the cleat to the pedal. A wedge should make no difference. Asymetric forces will make no difference either, because our system measures right across the width of the cleat. In fact, it measures separately at a number of points, so it will be able to provide information about asymetry in the application of force to the pedal (and about how it varies around the crank rotation).

- how does the sensor differentiate between pressure that turns the crank, and static pressure that is applied when a mountain biker is balancing on the pedals riding downhill out of the seat?

- I am an Australian physiotherapist, and very interested in the efficiency of foot to pedal force transmission. I still wonder when pedal and cleat manufacturers are going to wake up that standard pedal design should allow most force transfer to pass from the head of the first metatarsal (ball of the foot) to the pedal. This would avoid ITB friction syndrome and stress fractures of the 5th metatarsal. Cleat wedges are one solution though very few bike shops seem to fit them anywhere in the world. How will your sensor cope with cleat wedges or asymmetric force transmission through the cleat? i.e. more force through the medial aspect.

As for running, the power data will not be affected because the system can distinguish between pedaling and other movement, and will not record any power data while running.

With your cleat system, how do you hope to handle wear and tear from walking around? I guess the cleats will not be plastic but it would still be a challenge.
