I just tried to use my toes only and on my grand piano it's really uncomfortable but on my Roland I could do it. If you have a digital piano I see how you could think it's easier that way but I think it's a mistake.
You see, digital pianos usually have a much lighter pedal than grand pianos and the resistance is not realistic. By that I mean that in a grand piano when you press down the pedal all the dampers must be lifted up, which is quite heavy, but if you press down only a little, like 20 percent then the dampers are still partially resting on the strings and you don't feel the full weight of the pedal yet. On a digital piano the pedal has a more uniform springy feel.
Unfortunately, to really control the pedal you need to be very close to the point where the dampers are about to lift from the strings. To do that with your toes is very straining on the foot and it's much like using improper finger technique to press down on the keys instead of using arm weight and rotation.
