The loop jump is considered an edge jump because there is no kick off the toe pick. Although some define a loop jump as taking off from a back outside edge the skater is actually facing forward when the skate leaves the ice. The skater lands on the same back outside edge.

For advenced skaters a loop us usually entered directly from backward crossovers.
