Is a shoe mounted cadence sensor as accurate as crank mounted?

I just received the Wahoo speed/cadence sensor set to install on my new Cervelo P2. However, there is not enough room for the cadence sensor on the inside of the non-drive crank arm for installation. I've currently attached it to my left shoe, which shouldn't be a problem, as long as the sensor is accurate.

i would assume if it mounted in a way to be read 1x per revolution, you should be good.

I have the same issue with my P5.  I've tried a couple different sensors and none of them are thin enough on the crank so I have simply attached it to my shoe.  Seems to work fine. Doesn't drop data.  I've never done an official test to confirm accuracy, but it seems good enough for me.

Thanks Scott and Tom. That's what I needed to hear. Fit's snug on the front velcro strap of my shoe, so it shouldn't be an issue. I'll see how it goes.
