Super Cute

These shoes are exactly what I expected. I've only worn them a few times around the house so far. The fit seems just a tad smaller than I expected, but not enough to return. Bought them for a trip to Alaska. We are leaving in a few weeks... will update after I've had a chance to use them.

Love The Quality And Style But Sizing Is A Problem

I bought these for a trip to England, Scotland and Ireland in April. I wanted to get them early so I could break them in. I wore them one time to red rock amphitheater and my feet hurt so bad That I had to take the insoles out and loosen the laces to get through the rest of the night. I love the quality and the style but they are useless if they can’t be worn all day. I did size up like it said to do. Definitely disappointing and since I wore them I probably can’t return them.

Highly Recommend

Absolutely love these. I am a avid outdoors person, hiking and hunting. They are warm and just enough weight to let you know your sure footed. Keep your feet dry and warm. Highly recommend! Merrell foot wear is amazing. My first pair of Merrell boots are still in great standing. I purchased them almost 25 years ago. Which is why I keep coming back. I have purchased many footwear products over the years for both my husband and myself. Well made and durable.

Love These Boots! 10/10

I bought these boots specifically for a photography trip to Yellowstone knowing I would face variable weather conditions, potentially including wintry weather, and would want to be able to move around easily. We did in fact have three days of snow and every day started well below freezing. These boots were everything I had hoped for and more. My feet stayed warm and dry and they were super comfortable, so that meant I could focus on what I was seeing and enjoy my experience to the maximum. 10/10 highly recommended.

Hiking Boots.

The only reason I didn't give it a 5 is the heel of the sole extends behind the back of the shoe tripping me when I'm going downhill.

High Quality Boot!

My daughter wears Merrell boots and bought me a pair for Christmas. These are the nicest boots I have ever had! I wear a size 8.5 so she bought me a 9 and the fit is perfect. There is no breaking in period; put them on and go. We had a lot of snow so far this year but my feet have stayed warm, dry, and comfortable. If you’re looking for a wonderful boot, buy a pair of these.

Fit And Sizing.

Perfect fit if you size up a whole size. If you don’t size up, minimally thin socks will be required.

Mid-teens Kiana Replacement Success!

When my beloved Kiana's soles came unglued after a decade of use including the coldest and snowiest winters on record, I dug out the specs and went hunting for an equivalent pair. As it has been a very snowy winter I have had time to break them in and am quite happy. They are everything the Kiana's were, plus an easy in/out zipper and considerably lighter while remaining stable and toasty warm. Excellent traction and work well with my snowshoes, too. My only regret is that I didn't size up half a size as they are a smidge more snug than the Kianas were and I would prefer to use chunkier socks, but that isn't a deal breaker.

Amazing Comfort

Love these so much. I wanted to get another pair in black but they are not available....my loss. So comfortable with all the support needed.

Too Narrow

Boots were too narrow for me. Would love some boots in wider widths.

City Streets To Mountain Trails

These boots fit true to size -with my feet being on the wider side. They are comfortable, offer good support and kept my feet warm in snowy conditions. I wouldn't recommend for temperatures below -10°C. Also struggled with the zipper.
