Merrell  Siren 4 Thermo Mid Zip Waterproof Hiking Boots - Women's

Took my Merrells to Iceland and they did not disappoint. My feet were warm, dry and comfty during 10 days of adventures....waterfalls, glaciers, & hikes for miles. My husband loves his just as much.

Took my Merrells to Iceland in December. They were warm, and comfortable for walking a lot. Just what I was looking for!

I was so looking forward to having a pair of lightweight winter walking boots, but I'm really disappointed. I wore them on ONE walk and had a lot of foot pain - in two different places. 1) the boots are not wide enough in the toe box and they are not available in Wide sizes. 2) the boots cause pain on my ankle bone in the area of the lacing hook. It's also in the same area as the edge of the tongue. Not sure which factor caused the pain, but I could barely wait to get home and take the boots off. I have never had this problem with any other Merrell shoes or boots. It would be nice if Merrell would accept a return, but I don't see that option on the website.

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.

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.

I'm so happy with these boots. I've purchased many Merrell shoes and boots; always a size 9 but sized up to 9.5 and glad I did after reading how snug they are. Michigan winter hiking and my feet are warm. I also wear leg warmer over the top of the boots so that snow doesn't get around my ankles

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!

I've only worn them a few times, but so far they seem very comfortable to walk in and very warm. I ordered half a size larger, as suggested, and they fit well.

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.
