With its sporty look, the SIREN 4 THERMO MID ZIP WP W from Merrell is a women's winter boot halfway between a hiking boot and an après-ski.
This model is precisely designed to wrap around the particular contours of women's feet, while offering comfort, support and stability during long hikes. It keeps feet warm for longer, thanks to thick, reinforced insulation for extra warmth and protection, especially as this SOLARCORE® insulation is a lightweight insulating material originally designed for NASA. What's more, it has a waterproof membrane to keep out water and wick away moisture. To maximise protection, there is also a gusseted tongue to prevent debris from entering the shoe and an abrasion-resistant rubber back and toe cap. This model also features a brand new side zip for easy on and off.
Finally, Vibram IceTrek technology in the outsole ensures constant grip even in the wettest and slippiest conditions, and Vibram studs increase grip tenfold on difficult terrain.
