This shell-type ski-boot comprising a lower portion molded integrally with the sole and an upper made of a front quarter and a rear quarter pivotally interconnected and fulcrumed on the lower portion, is proveded with a telescopic traction device adapted to close the upper tightly and automatically when the front quarter is bent forwards. The telescopic traction device comprises a male member and a female member the relative axial sliding movement of which causes the rear quarter of the upper to move toward the front quarter. For this purpose, a pair of cables anchored to the rear face of the rear quarter are guided around the boot sides and inside a pulley-block comprising two sets of pulleys, one set being fixed and the other movable for varying the cable length and therefore the degree of tightening of the boot on the skier's ankle.
