Without wishing to piss on a parade- I had these and didn't get with them as the sole was too soft, so when you twisted to release the cleat required a huge movement, but I do have my pedals set at max torque on release.
A mate wore his for very many years & on long Audax's & swore by them, wanting to corner the remaining stock in his size, so he'd have a pair for life.
They're not good without the cleats as there's a big hole in the sole & no strength without the cleat.
