PROBLEM TO BE SOLVED: To provide an inline skate matching with human engineering and having excellent safety. SOLUTION: The inline skate is provided with a first roller 31, the first roller 31 is rotatable unidirectionally, and it is arranged off the grounding surface of the other rollers 3. When the first roller 31 is arranged at the front of the other rollers 3, the first roller 31 is unidirectionally rotated forward. When the first roller 31 is arranged at the back of the other rollers 3, the first roller 31 is unidirectionally rotated backward, and thus the pair of inline skates are provided with braking function of excellent ground gripping power and forward power applying points, and are provided with excellent safety and match match with the human engineering.
