Size and fit

This mid-top hiker is constructed using a gender-engineered last to make sure that it fits a woman's foot perfectly. Its upper features a padded tongue and collar, and an elastic mesh for a glove-like fit. The Merrell Siren 3 Mid Waterproof women's boot has a traditional lacing system with hook and webbing loops for a secure fit. There's also a pull tab at the back of the collar that helps get the foot into or out of the boot easily.

Excellent traction on all types of terrain

The Siren 3 Mid WP has the Vibram Megagrip outsole that is designed for hiking in all types of terrain. It has an aggressive lugging with a dept of 4.5 mm so it bites into the mud, loose dirt, and soil really well.

Excellent stability

The grooves on the heel help keep the boot stable when traversing uneven grounds.

Comfortable and supportive cushioning

Besides being shorter and narrower, women's feet tend to have lower insteps and slipper heels than men's. Additionally, women's Q-angle (the area just below the hip) leans on a slightly larger angle than men's, which increases pressure on the hips, knees, and back. This often results in pain or discomfort when walking. Taking this into consideration, Merrell has designed the Q-Form midsole which is specifically intended to deliver cushioning and support for female feet.

The Q-form midsole features a firm and supportive area to keep the foot centered, a second supportive area to keep it centered while the foot is lifted, and a soft region for cushioning as the wearer pushes off and takes another step. There's also cushioning in the toe area to help distribute the wearer's weight and pressure as she walks.

Excellent arch support

Additionally, the Siren 3 Mid WP comes with the Kinetic Fit Tri Removable insole that delivers comfort and arch support.

Waterproof and debris-resistant

This boot features a mesh and TPU upper with a padded collar and bellows tongue for keeping debris out. Lining the shoe interior is the M Select DRY impermeable membrane that prevents water from getting in. Sweaty feet are a common thing during long hikes, especially in the summer. Luckily, the Siren 3 Mid is treated with M Select FRESH antimicrobial agents that reduce shoe odor.

Prevents blisters or pain and secure fit

Furthermore, this boot has the Hyperlock molded TPU heel counter that keeps the heel in place, thus, preventing blisters or pain caused by friction or heel slipping. Completing the upper is a lace-up closure with hooks and loops for a secure fit.
