Skating warm up system

1. A skating warmup system, comprising:

a shoe, having:

a sole; and

a recess integral with the sole, extending upward into the sole and running parallel with the bottom of the sole, the recess having:

a rail; and

a spine composed of a semi-rigid material, the spine having:

a notch for slidingly engaging with the rail of the recess and securing the spine into the recess; and

a U-shaped bottom edge configured to come into contact with the ground;

wherein the U-shaped bottom edge has a width for providing a user with enough surface area on which to balance;

wherein the spine applies pressure to a user's foot, thereby mimicking a blade;

wherein the semi-rigid material allows for flexible movement of the sole when engaged with the recess; and

wherein the spine is fixed parallel to the sole of the shoe and substantially preventing the sole from coming into contact with the ground.
