Taking aggressive elements from approach shoes and blending them with the support of a pair of boots, the Salewa Men's Mountain Trainer Mid GTX Backpacking Boots provide the support, comfort, and aggressiveness you need when hiking above treeline. Their durable and wear-resistant suede upper is reinforced with a 360-degree rubber rand to protect against wear when hiking across rock-strewn trails and scree, and they are fitted with a GORE-TEX membrane, making the boots waterproof.
