I support the heels on the floor and toes clear of brakes for the following reasons.
During take off, you should only be using brakes during stopping, certainly not directional control.
Inadvertent braking will affect your take off run required TORR.
Performance charts make allowance for time to recognize a failure at V1 and then initiate braking. (assuming multi engine) This time takes into account sliding your feet a couple of inches up to the brakes, so rejecting a take off is not a valid reason for feet being on the brakes.
Using brakes in a tailwheel aircraft will bring you to grief.
I personally find using the pedals much easier with my heels firmly on the floor.
I also keep my feet ( toes) clear of the brakes during the landing, until the aircraft is well and truly on the ground.
I use this technique for light aircraft and jets.
