Product Overview

With 25 years of Merrell's women's-specific fit, the Siren 4  Thermo is uniquely engineered to cradle the distinct contours of female  feet, providing comfort, support, and stability even on the longest  hikes with 200 grams of added insulation for warmth and protection. Now  equipped with SOLARCORE® insulation, lightweight insulation material  initially designed for NASA, you never have to worry about warmth.  

The all-new medial zipper provides easy on/off, a new improvement made  directly from customer feedback. Merrell waterproofing on the upper will  keep your feet dry. With Vibram® IceTrek® underfoot, traction remains  consistent under the wettest, most slippery conditions.  For the first  time ever incorporating Vibram® traction lug for enhanced grip on uneven  terrain.
