Abstract: System for securing a foot or inner shoe (4) in a ski-boot or climbing boot, with tension elements (11) which extend from the instep to a hinged rear part (2) of the boot (1), in which the tension element or elements (11) are located in a fixable manner in the heel or Achilles' tendon region inside the hinged rear part (2) and pass over a deflection point (12) in the heel or angle region. Connected to the tension element or elements (11) is a clamping element (17) located between the deflection point in the heel or ankle region, which is linked with a clamping device (15) on the outer side of the boot. It is preferable that the tension element or elements (11) are placed in a crosswise manner in the region of the instep, whereby preferably the crossover point can be displaced in the longitudinal direction of the shoe (arrow 20).
