Comfy, flexible and breathable yet fully waterproof, the Salewa MTN Trainer Mid GTX is a lightweight trekking boot perfect for summer alpine adventures. The GORE-TEX Performance Comfort gives total weather protection and climate comfort, and a cushioning OrthoLite footbed wicks away moisture, helping to keep your feet cool and comfortable. Their flexible, cushioning midsoles boast dual-density Bilight TPU Technology, ergonomically shaped to cradle your foot and provide all-day comfort on longer hikes. At the ankle, the Flex Collar allows natural movement and adaptability during descents for extended comfort, even when you\'re carrying a heavy pack. And underfoot, the Vibram WTC sole delivers solid yet forgiving walkability. SALEWA\'s 3F System provides flexibility, support and a blister-free fit.
