GET THEM!!!

I am SOOO glad I got these!!! I shopped around—and I mean really shopped around—for the right boots for our trip. I tried Columbia, Sorel, UGGs, and several lesser-known brands, but I didn’t like the style or the fit for walking until I came across these!!! I absolutely loved these boots! They are incredibly comfortable, lightweight, and easy to walk in, even for long periods. I recommend sizing up half a size for added comfort, especially if you plan to wear thicker socks or double up. I did both and still felt comfortable—never tight or restrictive. I loved the style and fit; they look great while still being very practical. They’re easy to clean, feel durable, and are fully waterproof—perfect for having fun in the snow. The grip is solid and felt reasonably slip-resistant while exploring the icy cobblestone streets of Old Québec. Overall, these boots exceeded my expectations and are definitely worth the price! I can’t wait to use them again on our next snowy vacation! Read more

Best boots I've owned

These are exceptional. True fit, great walking comfort and warm feet! They are not high, so I need other boots for deep snow, but for every day use, I couldn't be more pleased. Read more

No break in period, so comfy but do size up!

Love that this came with zippers - that was a huge selling point. I found it easy to zip down/up. Bought it for a winter trip to Japan. I spent a really long time looking at reviews on sizing all over the web since our local Merrell doesn't have a winter line (I live in a tropical country) so I have no choice but to rely on reviews. I bought this specifically to hike in so I needed a slightly bigger fit to accommodate feet swelling for days of hiking. If you are doing the same, I highly recommend to size up. Based on Merrell size chart, I am a US size 7.5 women's regular, I went up to a size US 9 and with 1 thick wool socks and a change in insole (slightly thicker and bouncier), it fit perfectly with room for toes to wiggle. exactly what I need. It will really depend on your needs but if you intend to add 1 layer of thick socks, you need to size up AT LEAST 1 size bigger. If you will use just thin-medium thickness for socks and for just simple walks, at least half size bigger. Merrell hiking shoes that are at least mid-cut and higher, with insulation and padding really runs small. I will only recommend to go true to size if you have really narrow feet and don't intend to use it with winter socks. But then, this is a winter hiking boot so it is given to size up! It's so comfy too. No break in period at all. Read more

Quality and for icey conditions

I have been looking for boots for 2 and 1/2 months. I normally wear a 10, or 10 1/2. I have tried different brands always too small or I can't get into them, finally a pair of boots that I was able to get into. They seem nicely made. I will need these for snow and ice that we get in Nevada. The only reason I gave it four stars is because the laces if I use all the connectors then the laces too short. I don't consider myself a huge person but I'm definitely big boned. I just have to skip one of the connectors to be able to have enough lace to tie them. Read more

Easy on/off comfort!

I LOVE these boots. They don't keep my feet super warm, but they are comfortable to wear indoors at my day job. I didn't realize there was a zipper on the side - it makes them SO easy to slip on and off around the house for outdoor tasks. Read more

Disappointed

First let me say I love Merrell shoes and boots. These boots are good looking and comfortable. The Vibram sole is slip resistant. They are warm, however. On a walk on a 30-degree day, they were great. Working to scrape an inch of snow off my driveway on a 30-degree day, not so much. My feet were freezing (even with wool socks). I need a pair of boots for walking in the winter, but these didn't work out for me in cold, wet conditions. Definitely not as warm and comfortable as my 15-year-old Merrell snow boots. Read more

Go 1/2 to 1 size up

I normally wear a 6.5-7 but purchased 7.5 and they fit perfectly. They did not have wide widths so I got 7.5M. I have a wide foot and high instep so shoes are a challenge. These are extremely warm and would only work in cold seasons. I wear soft thin wool socks under them in Alaska. Great for hiking and seem pretty water resistant, sturdy ankle support and built to hold up in wet weather conditions. These are not rubber boots so don't expect a miracle if you step in the lake.
