Claim:
A safe roller shoe structure comprising: a body including a pedal; a base including four rollers, two of which are fixed on two front ends of two sides of the base, and the other two of which are fixed on two rear ends of the two sides of the base; the pedal including four integrally formed seats extending from two sides thereof so as to correspond to and to receive the four rollers; a shaft used to insert through each roller and each seat so as to position the each roller in the each seat; characterized in that a height of the pedal of the body is lower than a height of two rollers which are fixed on the two rear ends of the two sides of the base, thereby decreasing a gravity center of a user's legs in exercise; a rate of a diameter of two rollers on the two front ends of the base against that of the two rollers on the two rear ends of the base is 1:2; a range to increase or decrease a diameter of the four rollers is 15%.
