Has anyone tried or experienced mid foot cleat position?

Has one tried, (yourself or client), with mid foot cleat positioning…?? Have read read all info online, Steve Hogg, Gotz and Friel…, any of you Fitters tired/have had first hand experience?
Thanks

Yes, drilled a few shoes for myself. Worked well pedalling, not so well walking.

… but my other bike shoes didn’t have the cleat there, and in the mean time my calves had atrophied. Cyclocross was harder at first until they adapted again.

I went back to normal so my calves are happy in all my cycling shoes.
