Shimano SPD spindle/axle length

[FrothNinja]

I currently have what I presume is the standard 29mm between the crank and the pedal body on my Shimano PD-M520 pedals. When pedalling my shoe (size 11 UK) often rubs on the crank which is a far from ideal situation. Do pedals now only come with a standard spindle/axle length, or are longer ones available. My local bike shop's suppliers stock no such beast and Shimano no longer seems to manufacture them or do the extenders.
Hive help much appreciated - chopping bits off my feet not an option - as there are loads of cyclists with bigger hooves than mine.

Maybe try and reduce the q factor?

That's brave.
Personally I would reduce the BB width so my legs were straight rather than bowed out while riding as that forces the foot inward

Unless I have totally misunderstood what the q factor is (I may still have the wrong end of the stick but I did just double check 😉) I can't see how it would help with the afore mentioned gap. I'm already pretty much at the limit of lateral adjustment and it would have an adverse effect on my knees if I adjust the angle of my feet on the pedals.

Get a different shape crank and reduce the BB length. That will space out the feet

That's the sort of thing but only about 5mm is required

You can't really have an extender like those any shorter than your pedal thread length. I've used pedal washers (alloy sump plug washers) but a maximum of 2 per pedal.

How bad is the rubbage? If this is only a concern due to you noticing the polishing of the crank arm then ignore it and carry on. If you can feel it then maybe move your cleats slightly or consider alternative shoes?

You may find that shifting the cleats back as far as they will go reduces the extent your heal errs inwards.
On a point of detail I thought there would be rather few cyclists with "bigger hooves" than yours so I did a check.
Only about 3% of the male population take a shoe size higher than 11.

"11% of adults cycled at least once per week"

27M adult males in UK so 27M x 0.11 x 0.03 = 89,000 cyclists!! with "bigger hooves" than yours "loads". Am duly amazed: I wonder how many use cleats of any kind, mind.
(Note to self: need a new contract!)

Can you move your cleats inwards a little to stop or reduce the rubbing?

Worth the question, but these are spd cleats so they're on those two tramlines in the sole.

yes shoes have the slots for movement back and front and the cleats do side to side..

There is possibly 1mm left to move. I'll give them a good clean out and give that a try. With a bit of luck it may just do the trick

Make sure you move the cleat the correct way. It may be counter intuitive but you need to move the cleat towards the side of the shoe that is rubbing.
