My Feet are HAPPY

1 year ago

My daughter purchased a pair of these a year ago and really liked them. This year I bought a pair as well due to her recommendation, and I'm NOT sorry! These boots are FANTASTIC! They were comfortable to wear from day one with no breaking in period, and they are cute as heck to boot (pun intended). YES!! I live in the Pacific NorthWET and the boots have lived up to their waterproof reputation, keeping my feet warm and dry. The sizing is pretty right on as well. Technically, I'm a 6-1/2 - 7 Wide and I purchased a size 7-1/2 to allow for thicker socks, and these are a pretty sweet fit. I'd HIGHLY recommend them.

Good winter hiker

8 months ago

Fit slightly narrow in the toe box. I do not have wide feet and got my regular size. I wouldn't recommend sizing up or the heel will be sloppy. Break in well, overall nice boot good for winter trails. Warm, good traction, stay in place if you do the laces up right. I just wish shoe companies would quit thinking all women have fairy feet which are extremely narrow. As mentioned, I do not have a wide foot so if you do, I don't recommend.

Never without Merrells

Always buy Merrell for outdoors and work on our alpaca farm. Never have to worry about fit or even breaking them in! They’re always comfortable and durable!

Dislike the side zipper and tie up.

5 months ago

These boots state they are hiking, well don’t hike through a lot of snow. The moisture will soak through the laces and my side zipper comes down when I don’t noticed while snow ends up in my shoe. Just disappointed with these boots. They shouldn’t say hiking. More like casual wear, or casual hiking that doesn’t require you to track through snow that’s almost to your knees because your feet will soon be soaked.

No, I do not recommend this product

Grab the surface waterproof boots

8 months ago

These Siren 4 Mid Zip Waterproof are an option that holds a bit more on the walking surface because of the sole bottoms. I bought another pair of Merrell boots with a flatter bottom for different use. These are great for cool, wet days. I find them quite comfortable, like the zip (and do need to undo a bit of the lacing too — but it’s nice to have both as it makes on and off faster. Have used for walking the dog and doing errands. Have been warm enough, though I didn’t buy for cold weather per se. And it’s been rainier rather than snowy. Love that they are waterproof.

Boots made for rugid nature

1 year ago

Out of the 3 I purchased this may be the one I use for everyday wear in the outdoors. It is a pretty boot. The zipper is a nice concept and not sure how it will work overtime as far as duability but it may make taking off and/or putting on the boot easier which is a big PLUS. Alsom, warm, nice sole and I like the two hooks at the top of the laces for really adjust things if needed. The inside of the szipper has a bit of a liner that arises and is likely were the water proof portion stops - not sure how waterproof the zipper is yet.
