Using the cross-country ski boot legging structure, the leg can be fixed by the clamping portion 5, and the connection strength between the ski boot and the leg can be increased. The support of the ankle position can be increased by the setting of the heel portion 1; by connecting the heel portion 1 and the legging portion 4, the strength of the cross-country ski boot is improved, and the leg, ankle and foot can be made less likely to twist under the action of the heel portion 1 and the legging portion 4, the torsional rigidity is increased, which is beneficial to protecting the ankle and improving the performance of the ski boot; in addition, the fixing part 3 and the extending part 6 are detachably connected by a quick-release connection structure 7, so that the heel portion 1 and the legging portion 4 have left and right degrees of rotation, ensuring that the leg and ankle can move.

[0035] In some embodiments of the present invention, a midsole 18 is further included, which is arranged above or below the sole of the shoe body.

[0036] In some of the above-mentioned embodiments of the present invention, a midsole 18 is also included. The midsole 18 is arranged on the sole of the shoe body. By setting the midsole 18, the strength of the sole can be increased, so that the ski boots can fit the foot better, and the foot can better fit the sole during sliding.

[0037] It should be noted that the heel portion 1, the leg wrap portion 4 and the midsole 18 are all made of carbon fiber material. Carbon fiber material has the advantages of being lightweight and having good strength, which can greatly reduce the weight of the ski boots and significantly improve their performance.

[0038] In some embodiments of the present invention, the midsole 18 is integrally formed with the heel 1. The midsole 18 and the heel 1 are integrally formed to enhance the connection between the midsole 18 and the heel 1, thereby providing better protection for the ankle.

[0040] In some of the above-mentioned embodiments of the present invention, a reinforcing structure 19 is provided on the bottom surface of the midsole 18. The reinforcing structure 19 can increase the strength of the midsole 18 to ensure that the midsole 18 can better support the foot, and the reinforcing structure 19 extends from the heel position of the midsole 18 toward the sole of the midsole 18, and the reinforcing structure 19 stops at one-third of the front end of the sole of the midsole 18, which can avoid excessive strength near the toes at the front end of the sole, causing foot discomfort, and improve user experience.

[0041] Preferably, the width of the reinforcing structure 19 is smaller than the width of the midsole 18, and the reinforcing structure 19 is arranged in the middle position of the midsole 18, so that the thickness on both sides of the bottom of the midsole 18 is lower than the middle position, thereby enabling the corners to better fit the midsole 18 and improving the comfort of the foot.

[0042] In some embodiments of the present invention, the quick-release connection structure 7 includes a countersunk hexagonal screw 8, a retaining frame 9 and a flange nut 10. The retaining frame 9 is provided with a countersunk hole 11 for the countersunk hexagonal screw 8 to pass through. The countersunk hexagonal screw 8 passes through the retaining frame 9, the extension piece 6 and the fixing piece 3 and is connected to the flange nut 10.

[0043] It can be understood that the quick-release connection structure 7 can realize the quick release of the heel part 1 and the legging part 4, thereby improving the replacement efficiency of the legging part 4, and the replacement process is very simple, and can be disassembled using a hexagonal wrench and bent-nosed pliers.

[0044] In some of the above-mentioned embodiments of the present invention, the quick-release connection structure 7 includes a countersunk hexagonal screw 8, a retaining frame 9 and a flange nut 10. A countersunk hole 11 is provided on the retaining frame 9. After the hexagonal screw and the flange nut 10 are threadedly connected, the head of the hexagonal screw is located on the inner side of the countersunk hole 11, thereby avoiding the exposure of the hexagonal screw, preventing foreign objects from being caught, and protecting user safety.

[0045] In some embodiments of the present invention, a strap quick positioning structure is provided on the clamping portion 5, and the quick positioning structure includes a first vertical groove 14, a second vertical groove 15 and a third vertical groove 16 arranged in parallel, and a limiting protrusion 17 is provided in the third vertical groove 16. One end of the strap passes through the first vertical groove 14, the second vertical groove 15 and the third vertical groove 16 in sequence, and is clamped on the limiting protrusion 17.

[0046] In some of the aforementioned embodiments of the present invention, a strap quick-positioning structure is provided on the clamping portion 5, which is used to clamp the clamping portion 5 to the leg. The strap quick-positioning structure includes a first vertical slot 14, a second vertical slot 15, and a third vertical slot 16. A limiting protrusion 17 is provided within the third vertical slot 16. After the strap is passed through the first vertical slot 14, the second vertical slot 15, and the third vertical slot 16, the limiting protrusion 17 positions the strap, ensuring that the strap can be quickly removed and installed, significantly improving the efficiency of strap replacement.

[0047] In some embodiments of the present invention, the front end of the clamping portion 5 is provided with an outwardly expanding portion 12 extending outward.

[0048] In some of the above-mentioned embodiments of the present invention, an outward expansion portion 12 is provided on the clamping portion 5, and the outward expansion portion 12 expands outward, thereby avoiding collision between the clamping portion 5 and the shoe body when wearing the shoe, thereby avoiding damage to the shoe body, and is beneficial to protecting the shoe body.
