Abstract: An article of footwear including a sole and an upper, a lateral quarter and a medial quarter. A device for tightening the upper includes a first lateral lace strand and at least two points for connecting the first lateral strand to the lateral quarter, as well as a first medial lace strand and at least two points for connecting the first medial strand to the medial quarter. Each lateral or medial strand includes a lateral intermediate portion or a medial intermediate portion, respectively, which extends between two connecting points of the same lateral or medial quarter, without being guided by a connecting point of the other lateral or medial quarter, a connector connecting the lateral and medial intermediate portions of the lateral and medial strands, respectively, the connector enabling the sliding of at least one of the lateral and medial strands.

Abstract: An article of footwear including a sole and an upper, the upper including a seat adapted to nest the user's heel, the seat including a first stiffener, and an arrangement for varying the size or volume of the seat provided by the first stiffener, between an expanded position, for which the volume of the seat is relatively large, and a retracted position, for which the volume of the seat is reduced.

Abstract: A sports boot, particularly for ice climbing. The boot has an upper, a rigid sole directly fixed to the upper, and climbing crampons directly fixed to the rigid sole. The rigid sole can be made of a composite material or metal. It is provided with threaded inserts capable of receiving screws for fixing the crampons.

Abstract: A walking boot with a high upper, of the type having a tongue made of two lower and upper portions corresponding to the instep and to the lower leg, respectively, of a user wearing the boot. The tongue includes a structure that fastens a tongue reinforcement that extends along at least a part of the two portions of the tongue to increase the rigidity thereof.

Abstract: Sports footwear for cycling use, in which a latching member is provided to cooperate with a bicycle pedal and is detachably attached to the sole with a rigid insert. The footwear of the invention includes a sole and an upper extending upwardly from the sole. A reinforcement plate is fixed on an upper surface of the sole and is positioned beneath the peripheral edge of the upper. Further, an insole is positioned above the peripheral edge of the upper, the peripheral edge thereby being situated between the insole and the reinforcement plate, with the thickness of the peripheral edge of said upper defining a housing. The rigid insert has an upper portion that is adjustably positioned on an upper surface of the reinforcement plate, the upper portion of the rigid insert having a thickness no greater than the height of the housing defined by the thickness of the peripheral edge of the upper. The latching member is detachably connected to the insert.
