Mammut Mercury IV Low GTX Men's Hiking Shoes Black-Titanium

The Mercury IV Low GTX stands apart from typical lightweight hikers by combining a supple Terracare® nubuck leather upper with a softshell collar and a GORE-TEX Performance Comfort Footwear lining. This construction keeps feet dry through stream crossings and afternoon showers while allowing the ankle to flex naturally on uneven ground. A Vibram® Frog Grip outsole delivers confident traction on wet rock, damp roots, and loose gravel, and the EVA wedge midsole with 3D Memo Foam footbed cushions every step without adding unnecessary weight. At 860 g per pair (UK 8.5), it is light enough for fast day hikes yet supportive enough for multi-day treks with a light pack.

Highlights

• Waterproof GORE-TEX Performance Comfort Footwear membrane
• Terracare® nubuck leather and softshell upper for durability and comfort
• Vibram® Frog Grip outsole for reliable grip on mixed terrain
• 3D Memo Foam footbed and EVA wedge midsole for all-day cushioning
• Elastic GORE-TEX tongue construction keeps debris out and fit secure
• PFC-free DWR treatment and Terracare® leather for reduced environmental impact

In daily use

From the first step, the Mercury IV Low GTX feels broken-in yet supportive. The lacing system locks the midfoot without pressure points, while the padded softshell collar prevents rubbing on long descents. The 12 mm heel drop encourages a natural stride, and the flexible forefoot allows the shoe to roll smoothly over rocks and roots. On warm days, the GORE-TEX lining breathes well enough to prevent overheating, making these shoes a versatile choice for everything from quick local trails to extended backcountry trips.
