ABSTRACT:
A sports boot that includes a tightening device cooperating with a series of return elements for tightening an upper portion, each return portion including a closed loop made of a flexible and traction-resistant material, wherein the return element includes a guiding portion connected to the loop and has a sliding surface for the passage of the tightening device within the loop along a passage plane P, the guiding element having enough stiffness in the plane P to resist deformation when the tightening device is placed under tension. The tightening efficiency is thus optimized by reducing friction. The size of the return element is limited in order to provide greater comfort in case pressure is exerted by an external element.
