Made for crisp mornings, snowy strolls, and everything winter brings, the Siren 4 Thermo Lace Waterproof wraps your feet in cosy warmth with a women's-specific fit designed for all-day comfort.
The Siren 4 Thermo Lace Waterproof walking boots feature an upper made of pig suede and other leathers, designed to maximise comfort in cold conditions. These materials provide waterproofing to wet and snowy conditions along with superb durability. To enhance the watertight design, a waterproof membrane has been implemented into the upper, along with a TPU waterproof shell for additional protection. Within the boot, a faux fur lining keeps your toes nice and toasty while wicking moisture away from the feet and works in conjunction with 200 g of PrimaLoft Gold Eco Series insulation. This insulation has top-of-the-line thermal efficiency with a high percentage of post-consumer recycled content, offers a good warmth-to-weight ratio, and performs well even when wet for warmth in wet conditions. The upper also features a bellows tongue to prevent dirt and debris from getting within the boot, along with a 100% recycled traditional lacing system for effectively locking the midfoot into place. Finally, a medial side zipper can be found on the inner side for easy on and off.
Featuring Merrell's FloatPro foam, the midsole of the Siren 4 Thermo Lace Waterproof boots is durable yet comfortable underfoot. The EVA-based foam ensures your feet are provided with a cushioned base for long days out on the move in forever-changing conditions, enhancing the energy return through your stride to keep you motivated and pushing on over tough terrain. To ensure double the comfort, a FloatPro footbed is also featured within the shoe to further support the feet and enhance padding. The footbed has a 100% recycled mesh cover to boost breathability underfoot to prevent moisture building.
Offering improved grip on extremely cold, icy or snowy surfaces, a Vibram ICETREK outsole has been utilised. The construct of this outsole features a soft rubber that is safe for indoor surfaces, ensuring it does not scratch or damage floors. Additionally, it does not absorb liquid or dirt, helping to maintain the boot's lightweight design. The softness allows the compound to adhere to smooth surfaces and to support aggressive terrain in order to improve traction. The sole design utilises small pointed lugs and large supporting surfaces for confident movements on challenging surfaces.
