La Sportiva Trango TRK GTX Mountaineering Boots Sportiva Trango TRK GTX (Yellow / Black) These are ultra-light mountain boots perfect for hiking and backpacking. The new "Thermo Tech Application" technology creates a thin, lightweight upper that is both waterproof and protective. They incorporate breathable and waterproof Gore-Tex and feature the 3D Flex System, which protects the ankle without restricting movement. Price: ¥30,470 Weight: Approximately 580g (1/2 pair) Color: Yellow x Black Size: EUR41 (26.1cm) I've used these for about seven years, including in the Northern Alps. They have scratches and scuffs, as shown in the photos. One of the lace hooks on the right boot is missing. The Gore-Tex seems to be working, and I don't think water will get in. The fit of Sportiva's Mountain boots is superb. For those who want to try them out!! The original box is also included. Instant purchase is OK.
