Excellent grip and durable

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.

Excellent traction

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.

Comfortable cushioning

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.

Shock-absorbing cushioning

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.
