Toe clips enable the bike rider to lift the pedal to enhance total torque. When I was studying ballet in my younger days, I used junior toe clips to take full advantage of the articulation of the foot. The junior toe clips put the axis of the pedal below the ball of my foot enabling me to use the pointing and flexing of my foot to enhance the torque of my pedalling. The ballet toe go one step further by putting the axis of the pedal slightly ahead the ball of my foot. The feeling is invigorating to know that you are using all possible movements to propel yourself.
