A roller skate (100) includes a support (2a) attached to a skater's foot which has a central longitudinal axis X, an inside and an outside, a forward end, and a rear end. First and second non-aligned axles (9 and 10) are attached to the forward end of the support (2a) and extend sideways from the inside of the support, with the second axle (10) being closer to the center c of the skater's foot then the first axle (9). Third and fourth non-aligned axles (18 and 19) are attached to the rear end of the support (3a) and extend sideways from the outside of the support, with the third axle (19) being closer to the center c of the skater's foot than fourth axle (18). A pair of large wheels (12 and 16) are mounted for rotation having diameters approximately equal. A pair of small wheels (13 and 15) are mounted for rotation having approximately equal size diameters which are approximately half diameter of the large wheels (12 and 16).
