C3fit Focus Support Long Tights フォーカスサポートロングタイツ　WOMENS 3FW17122 ¥15,400 (tax included) I wore these 2-3 times for mountain climbing after purchase. The edge of the knee support part is partially peeling off, but I didn't feel any discomfort when wearing them. Supports knees, hips, and thighs. Reduces stress on the hips and knees. During trekking, the weight of the backpack mainly rests on the hips, which is a high-stress area. Support is provided to cover the entire pelvis, firmly protecting the hips. Also, the reason for knee pain during descents is often due to fatigue causing a decrease in leg muscle strength, making it impossible to bend the knees upon landing, and thus the impact is not dispersed. By providing firm support to the knees, thighs, and calves, the burden on the legs is reduced, protecting the knees. Comfortable features for long treks A front zipper is used for easy on and off, such as when changing clothes or using the restroom. You can also adjust the waist tightness by unbuttoning the front button after meals. Also, since you often lift your legs during ascents, the hamstring (back of the thigh) support is intentionally omitted to make it easier to lift your legs. Provides a comfortable wearing experience even during long treks.
