Redefining the high performance, amphibious hiking boot. TR1 Merge 2.0™ is an exceptionally breathable, ultra-lightweight hiking boot that combines stability, grip and ventilation to provide performance on both wet and dry trails.
EXCEPTIONAL GRIP
Sticky yet durable G.15 Rubber™ + Trail Grip™ outsoles provide exceptional grip on wet and dry surfaces. Non-marking.
BALANCED GEOMETRY™
Zero drop, Level Footbed® + a wider toe box respects your foot's natural position while increasing balance and stability.
The TRI Merge is the perfect blend of support and performance. It has enough structure to cushion and protect your feet and ankles without being too heavy or overbuilt. The tread provides great, long-lasting traction in all conditions and I've never worn a low boot that dries so quickly. It's my go to mid-top hiking boot for everything from a weekend camping trip to a long-distance thru hike.
Jennifer Pharr Davis | Record-Setting Thru-Hiker
ULTRA LIGHTWEIGHT
