A wheeled skate having a rigid chassis secured to a boot and having a heel plate (54), a sole plate (55) and a pair of downwardly depending parallel webs (56,57) between which three in-line wheels (12a) are mounted. Each wheel (12a) is at least half as wide as its diameter and has its floor engaging surface formed by a part of a sphere. The middle wheel is lower than the front and rear wheels by a distance D of 2.5 to 4.5 cm. The rear wheel does not project more than 10 mm behind the rearmost part of the boot, the front wheel does not project forwardly of the boot at all, the middle wheel is spaced a distance A from the rear wheel and a distance B from the front wheel, A + B is at least 70% of the overall length C and <MATH> lies in the range 0.06 to 0.09. i
