Update- So I switched to the M324 pedals and the easier cleats. That made a huge difference, much easier to click in and out and the feet feel much more supported.However, given my wide feet I ve been riding size 9 or 44 shoes which, I now realise, can't give me a midfoot position and I really notice a loss of power generally and especially when climbing a hill. So, I am now looking at Lake shoes which offer a wide 43 shoe. Lets see what happens.
