A boot having an external sole on which is mounted an upper open towards to the front, to enable passage of the foot and including to this end, an internal and an external quarter connected to each other by a closure system which includes a flexible link along a predetermined alternative path, a series of return elements located in a fixed manner on each side of the quarters in the vicinity of their respective edges located across from each other and defining a lacing zone, such that when an action is exerted on the two free ends (A, B) of the slack ends of the flexible link via traction members, such members tighten quarters, via return elements, so as to bring them closer to one another and consequently ensure internal retention of the foot, wherein the lacing zone can be broken down into three tightening sectors, i.e., a first primary tightening sector; a second primary tightening sector; and a third secondary tightening sector whose tightening is undertaken after that of the first and second sectors by the progressive transmission of traction forces exerted on the slack ends of the flexible link from their free ends. |
