- A multi-season backpacking boot, the Astral TR1 Merge sports a breathable and quick-drying upper, complete with protective overlays. Its over-the-ankle design is rounded out with a padded mesh tongue.
- Absorbing shock on every landing is the TR1 Merge’s stout midsole made of ethylene-vinyl acetate (a.k.a EVA). What keeps users planted on slippery surfaces, on the other hand, is the footgear’s aggressively lugged, non-marking rubber outsole.
The Astral TR1 Merge is an adequately true-to-size, mid-cut boot for male and female trekkers. It comes in standard width. It is offered in full and half sizes. Its lace-up closure makes fit personalization possible. The pull loop on the heel speeds up on and off.
Delivering traction on the trail is the TR1 Merge’s high-friction and abrasion-resistant rubber outsole. Based on the Astral-exclusive rubber compound called G.15, this component—with its aggressive, 5-millimeter lugs—grips on both natural and man-made surfaces, may they be wet or dry. It possesses a decent amount of flex and is non-marking to boot.
Astral engineers extended its forefoot tip all the way to the upper. In so doing, they have given the gear extra forefoot protection.
Serving as the boot’s stabilizing platform is its EVA midsole. Its noticeably thick construction is designed to cushion the foot against sharp and pointy hazards as well as mitigate shock with every stride. It comes engineered with Astral’s Top Shank—an added component that provides additional medial support, thereby lessening foot fatigue.
Right on top of this beefy layer is the TR1 Merge’s removable insole. It delivers added cushioning, and since it is Polygiene treated, proactively prevents odor buildup.
This Astral gear encloses the foot in a fast-drying, breathable upper made of canvas. Its protective overlays—the heel and toe caps—are made of thermoplastic polyurethane (TPU). It is crafted with a heel counter which grants extra rearfoot stability. The boot’s interior is also padded (around the collar and on the tongue) for a comfy backpacking experience.
The gear’s closure system features eyelets of different types. The lower half is comprised of D-rings which are made of brass, while the remaining ones from the top of the instep up are fabric loops and regular eyelets.
