-First in line in its features is the Megagrip outsole powered by Vibram which is known for its robust grip on wet and dry surfaces. Such an outsole is made up of a “sticky” compound that is long-wearing.

-The shoe is lined with the Gore-tex membrane which has proven waterproof performance. 

-It also features a dual-density midsole and a heel-centering technology that provides gender-engineered alignment and comfort.

The Siren 3 GTX is a low-cut hiker made with a highly elastic TPU upper. This material wraps the foot for a nice, comfortable fit. It integrates a traditional lacing system with slim laces that make tightening or loosening up the fit easy.

Much of the great qualities of this Merrell hiker can be attributed to its rugged outsole system. The Vibram Megagrip is made of a proprietary rubber compound that is very long-wearing. 

Its major qualities include stickiness which makes it easy for hikers to walk on rocky or uneven grounds. The lugs are 4.5mm deep for strong traction. The Megagrip outsole is also touted for its high level of traction on slippery, muddy and wet surfaces. And just as it’s good on trails, the Siren 3 GTX also performs well on city streets.

Women’s feet are biomechanically different from that of men. Aside from being shorter and narrow, they tend to have a low instep height and a slimmer heel. For the Siren 3 GTX, Merrell has integrated QForm Technology in designing the midsole. It is meant to provide stride-specific cushioning for female feet. 

The QForm works by absorbing shock in the heel and centering it on contact to improve stability. It also provides cushioning on the toe area for added comfort.

The shoe also comes with a removable EVA insole that offers support to all three arches of the foot.

This women’s hiker has an upper made of TPU and mesh. TPU (Thermoplastic polyurethane) has special properties that make them a popular choice for footwear products. These include high abrasion resistance, high shear strength, and high elasticity. Meanwhile, mesh fabric has significant breathability and quick-drying properties.

The Merrell Siren 3 GTX has the Gore-tex lining that acts as a waterproof barrier. Lastly, the shoe features a molded TPU heel counter for protection, bellows tongue for keeping the debris out, and web lacing system for a secure fit.
