An inline skate whose arrangement of wheels has a zigzag shape is provided to maintain not only the balance safety in front and rear directions of the inline skate but also the balance safety in left and right directions. An inline skate whose arrangement of wheels has a zigzag shape comprises four wheels. Based on the center line connecting a first wheel in the front of the inline skate and the fourth wheel in the rear of the inline skate, the second wheel from the front of the inline skate is moved in a direction of a big toe, and a third wheel from the front of the inline skate is moved in an outer direction of the heel part from the center line. First and fourth wheels are used to maintain balance in front and rear directions, and second and third wheels are used to maintain balance in left and right directions.
