Have you used the clutch?

I have a kinesis advantage pro, which came with a footswitch.

I quickly found out that my feet are very clumsy and can't come close to keeping up with my fingers. Also I couldn't find a way place the switch that feels ergonomic and comfortable.

I tried to use the switch again last summer while reading a long kinetic novel but came to the same conclusion: it's very clumsy and just doesn't feel comfortable at all.
