keeping feet correctly on pedals

[Dusty Bin]

I agree with Sully above. Having the correct saddle height will help achieve a better foot position. If he can touch the ground while seated, the saddle position sounds too low. Kids should be encouraged to stand over the bike (off the saddle) when stopped.

I agree with ianrauk.

It's a trivial issue which will sort itself out. It has to if the next change is to clips or clipless pedals and shoes.

The main downside of pedalling with the arch is the increased possibility of toe to wheel contact.
