Abstract: Water-proof protective gaiter for a boot having a tubular shape, of the type comprising, on the one hand, a lower portion (1) covering at least partially the upper (2) of a boot (3) in a front area of insertion of the user's foot, then of closure, whose lower end circumference (4, 4A) is designed to adopt the contour of said upper (2), and, on the other, an upper portion (6) designed to enclose the lower leg of said user. An at least partially peripheral flap (8) forming an extension of said circumference (4) extends from at least a portion of the end circumference (4) of the lower portion (1) of the gaiter, so as to extend the range of protection of the gaiter beyond this circumference.

Abstract: A sports boot, especially for cross-country skiing or walking, including an upper, a reinforcement extending at least vertically upwardly on each side of the heel, and a rigid collar encircling at least the ankle, and connected by its sides to the reinforcement, by two anchoring systems located on each corresponding side of the foot, and enabling the rotation of the collar along a substantially transverse axis with respect to the upper of the boot. At least one of the anchoring systems is effective for varying the position of the corresponding side of the collar with respect to the reinforcement, for enabling the inclination of the collar with respect to the median vertical plane of the boot and/or the rotation of the collar around a substantially vertical axis.
