Good to know

  • Garmont made a few modifications to this iteration of the Syncro Plus GTX. From a 2.2 mm top grain leather, it now uses a 2.2 mm full-grain leather for its upper. The designers also changed the waterproofing membrane. Previously, it was the Gore-Tex Sierra. The second version now has the Gore-Tex Performance Comfort liner. The components of the trademarked Anatomically Directed Design (a.d.d.) were kept in this version. They work with the human foot to deliver on-trail performance.
  • The latest version comes with a gender-specific footbed for optimal comfort. The brand retains the FrameFlex Lite insole with a nylon frame for stability. The PU midsole renders cushioning and absorbs shock from impacts.
  • Still providing underfoot support is the Vibram Ground Control. Its self-cleaning and open lug pattern provide traction and stability on various surfaces.

The Garmont Syncro II Plus GTX caters to male and female backpackers. It is a fairly true-to-size footwear offered in medium width and standard sizes. With the Performance  fit, this pair has a spacious instep and forefoot volume. The toe box  is designed with a straighter shape to have a room for the natural position of the big toe. This layout enables the toes to render a more balanced and propulsive stride. The differential ankle pads (which belong to Garmont's a.d.d.) deliver a secure heel lockdown. A precise fit is also granted by these parts to the ankle bones for support and stability.

The Syncro II Plus GTX from Garmont uses a Vibram Ground Control outsole. Its textured lugs deliver traction on hard surfaces. The reversed chevron lugs in the rearfoot area act as brakes and grant security during descents. Meanwhile, the lugs on the forefoot assists during ascents and acceleration.

The midsole of the Syncro II Plus GTX is made of polyurethane (PU). It is partnered with the FrameFlex Lite which is a lightweight insole with a full-length, full-width nylon frame. The central zone is thickened to support the rearfoot. The medial-lateral slashes which intersect at an anatomical angle enhance the forefoot flex.

The footbed of this backpacking boot has an open cell construction which makes it resistant to compression. It dissipates shock making every stride comfortable. The ECO-PU footbed for men has an antimicrobial layer which controls odor and moisture. The women’s ECO-PU, on the other hand, has an additional 3mm EVA at the heel and midfoot area. It aims to support and address the natural biomechanics of women.

The Syncro II Plus GTX from Garmont has a 2.2 mm full grain leather upper. It has a rigid composition. Hence, it is the strongest and most durable type of leather. With its tight framework, the level of resistance to moisture is high. Its appearance and permanence improve over time and use.

Taking care of the waterproofing and breathability is the Gore-Tex Performance Comfort. It lines the upper of this backpacking boot with its modest insulation and offers an all-season comfort—from warm to cold conditions. 

The Anatomically Directed Design or a.d.d.  from Garmont includes many features. An asymmetrical cuff (which is higher in the inside than the outside), warrants better movement and stability when the user is scrambling or traversing. Its anatomical tongue follows the shape of the top of the foot to the ankle for enhanced control and comfort. The precision lacing allows the foot to flex naturally for an on-the-spot comfort.

Furthermore, it has a rubber rand at the toe for protection against accidental bumps. The lacing hardware is a combination of hooks and D-ring for a speedy and precise lace-up closure.
