Good to know

  • The Merrel Siren Strap Q2’s strappy upper is a combination of waterproof nubuck leather and webbing. It features two adjustable straps—one at the ankle and another at the forefoot.
  • Providing stability and cushioning is the Q Form 2 dual-density midsole. It is engineered with a heel-centering technology for gender-specific foot alignment and extra comfort. Additional cushioning is care of Merrell’s In-Board Compression Molded Footframe.
  • On the underside of the sandal is yet another Merrell technology called M-Select Grip—the footwear's outsole. As its name suggests, this proprietary outsole offers surface traction on rugged terrain, thanks in no small part to its treads and low-profile lugs.

The Siren Strap Q2 is a fairly true-to-size Merrell hiking sandal specially crafted for the female crowd. It comes in standard width and is offered in a number of whole sizes. The upper’s pair of adjustable straps makes getting a personalized fit possible. The strap at the middle of the sandal has a stretchy base which allows for a dialed-in instep fit. The padding on the interior of the upper grants comfort. 

Come rain or shine, Merrell’s M-Select Grip outsole enables wearers to take on tricky trails with adequate traction. As it is made of special compounds, this outsole is granted a level of resistance to abuse and wear and tear. Its surface is also amply peppered with self-cleaning lugs, having a general depth (or height) of 3 mm. 

The Merrell-exclusive Q Form 2 midsole is what provides hikers stability and underfoot cushioning in their outdoor adventures. Its dual-density construction adds cushioning at key zones, thereby making transitions comfortable. At the heel of the midsole is a groove where Merrell’s Air Cushion technology is embedded. This extra component contributes to the sandal’s overall shock absorption.

For added comfort, the engineers equipped the Siren Strap Q2 with a non-removable, textured footbed. It is lightweight yet can withstand considerable stress, thanks to the material of which it is made—ethylene-vinyl acetate or EVA. This footbed also has a hump across the forefoot zone (underneath the spot where the toe joints rest) which helps prevent underfoot slippage, especially during descents. 

The Siren Strap Q2’s waterproof upper combines the lightness of webbing and inherent toughness of nubuck leather in a simplistic yet versatile design. It has a neoprene lining by Lycra for internal cushioning. The adjustable ankle and forefoot straps are sealed with hook and loop fasteners. The buckles serving as the straps’ joints are rounded and beveled for smooth and easy adjustments. Connecting the inner side of the instep strap to the midsole is a piece of elastic fabric resembling garter. For a convenient on and off, the upper comes complete with a pull tab which is made of a durable, synthetic material.  

  • Cleaning the Siren Strap Q2 generally involves brushing away dirt using a soft bristled brush. If it gets especially filthy with heavy dirt, wash it in warm water with a mild soap. Rinse thoroughly and let it air dry.
