Why We Like The Merrell Siren 4 Thermo Mid Zip WP Boot

When we won't let winter interrupt our hiking addiction, we slip into the Merrell Siren 4 Thermo Mid Zip WP Boot to keep from slipping and sliding on the trail. This winter hiking boot is snowproof with its waterproof membrane and full-grain leather uppers, and it's built to keep our feet warm with 200g Primaloft Gold Eco insulation packed inside. Snow and ice would keep us inside, either, thanks to Vibram Arctic Grip rubber outsoles, which are made for cold and slippery winter conditions. Made with a women-specific fit, the Siren 4 Thermo lets us enjoy 4-season hiking with warm feet and good grip on snowy and icy surfaces.

My 10th Pair of Merrell's

These are my 10th pair of Merrell's shoes. I bought them online without trying them on in store, which alone says a lot about how much I trust the brand, the quality of their shoes and the aftersale services. These boots give my 40 years old feet just enough arch supports for long distance walking and hiking. They are warm and water resistant. Well designed for comfort. Well bulit to last. I have worn them a couple of times in different weathers, wet or dry (location is Albany in Western Australia) before leaving this review here. Will buy again for sure.

Comfortable and warm

Received and immediately popped on and felt great. Have been wearing them in on town walking and some hills and beaches. Getting ready for a Nordic winter so am looking forward to wearing in snow and ice!! In the meanwhile the Tassie winter will suffice!!

Fantastic Quality Boots

These boots are wonderful, warm, supportive, comfortable and protective. I wont be taking these off during winter! They felt fabulous from the first wear, no breaking in required. They are quite fashionable looking too so I also wear when running errands on wet days and look great with leggings.

Siren = Comfort, style and durability

After a 10km bushwalk through rocky, muddy, dirt trails, many stairs, incline and decline, as well as a fair distance of concrete path , my feet felt as fresh as when I started. I didn’t worry about ankle roll at all, felt safe and snug in these boots. I wore bamboo socks which didn’t create any friction or heat. Comfortable, impact absorbent and they look great too! I am so happy with these boots. High recommend.

Comfortable and warm

Bought these to wear in Winter in Japan. Wanted to be able to unzip and slip off. If laced all the way that’s not possible. They’re super comfortable and warm though. Great walking shoes.

These boots were made for walking

Great for walking and solid underfoot. Definitely waterproof and keeps my feet warmer. Zip can be a little stiff to fasten.
