The difference is the just the last part of the combo---the toe loop and flip....
:flip:
this is a toe-assisted jump from the left back inside edge and right toe pick. Like the salchow, the usual entrance is a three turn, but usually from a straight-line approach instead of a curved one. (This jump is sometimes called a "toe salchow" in Europe.)
The flip and toe loop look much alike and even experienced observers sometimes have trouble distinguishing them. Here are some things that may help:
For the flip, the skater picks with the same foot they land on, while with the toe loop they pick with the opposite foot.
For the flip, the skater picks inside the curve of the jump, while with the toe loop they pick outside the curve.
For the flip, the skater turns away from the picking foot as they jump, while with the toe loop the skater jumps towards the picking foot.
:toe loop :
the approach is on a right back outside edge. The skater then reaches back with the left foot and jabs the toe pick into the ice to provide assistance for the jump at takeoff. Often done as the second jump of a combination, or as a solo jump after an inside three turn. If the jump is approached from an outside three turn and step instead, it's sometimes called a "toe walley"; technically the toe walley is supposed to be done from an inside edge, but otherwise the two jumps are considered equivalent. (The toe loop is the same jump that roller skaters call the "mapes", and that is called a "cherry flip" in some parts of the world.)
:loop:
this is also an edge jump, with takeoff from a right back outside edge. Usually skaters approach this jump by skating backwards on two feet, with the left foot crossed in front of the right. Often they look like they are sitting in an invisible chair. Unlike the salchow, there's no swinging of the free leg into the jump; the skater simply springs upward in a cross-legged position. (In Europe, this is also known as a Rittberger jump, after its inventor Werner Rittberger.)
