Merrell Siren 4 Thermo Mid Zip Waterproof Women's Walking Boots
A winter-ready boot with a women's-specific fit that combines function and all-day wear-ability.
Waterproof Full Grain Leather Upper
Utilising a full grain leather construction, the Siren 4 Thermo Walking Boots have a comfortable, durable upper with the ability to keep feet cool, as well as dry thanks to the waterproof membrane. The leather materials provide an enhanced level of protection against, knocks and bumps, dirt and debris, for boots with long-lasting properties. A Merrell waterproof membrane features to further ensure that water, rain and damp conditions are kept on the outside, therefore keeping feet dry and cosy no matter what the conditions are. A bellows tongue helps to keep out debris while a protective and abrasion-resistant rubber heel and toe cap helps to protect you against rocks and uneven surfaces. The recycled bungee laces and toggle closure keep feet locked in and secure, ensuring in-shoe slippage is prevented. Primaloft Gold Eco Series synthetic insulation resides in the upper to provide exceptional warming properties to keep you warm should the temperature reach below freezing while a Cleansport NXT treatment prevents the build-up of odour-causing microbes, keeping the boots fresher for longer. Completing the upper is a YKK zip to assist in putting the boots on and off.
FloatPro Foam Midsole
Within the midsole Merrell's signature FloatPro Foam has been used to ensure a light, durable ride. The midsole ensures ample underfoot cushioning to reduce the impact placed upon the feet on tough trails whilst remaining as lightweight as possible so you'll never feel weighed down. The lightweight midsole offers supreme cushioning and support to key areas like the arch and heel, holding the foot securely in place for a smoother transition and wear. By supporting these key areas of the foot, the midsole material can also help to offer enough support to help prevent discomfort and possible injury.
Vibram Icetrek Outsole
Designed with a technical compound, and exceptional overall performance, perfect for outdoor activities, the outsole construction of the Siren 4 Thermo has a Vibram Icetrek outsole. The outsole is designed to offer traction and support in all conditions. This construction allows the boots to have some flexibility for more comfortable stepping. The advanced rubber compound provides greater traction on very cold, icy, or snowy surfaces in even the most extreme temperatures ensuring you have confident footing no matter where you choose to explore.
