The fit and the materials of this boot are really great. They would be comfortable except for the fact that the ankles are exposed and the cold and snow get in. They are way too low. They're not really boots in fact, more like shoes. It's impossible to hold pants around them, they always slip off on the back because there is so little wiggle room. You I have to always wear them with good gators that go low on the back, and ironically they don't have gater hooks. I wouldn't have but these shoes but i had to get higher boots replaced and there weren't any other wide models available.
I have Merrell shoes before and added to my foot gear with these and they did not disappoint. The shoes work well for me, fit is great, they walk well wuth plenty of support and keep your feet flat and level on the ground, and they look great too. I wore these to a Buffalo Bills game, on 11-16-25. The temperature was around 38 degrees, with wind chill down to freezing. I was wearing electric socks. However, I never turned the socks on and my feet never got cold. I was wanting to see how long my feet would stay comfortable and I should have known, they did not disappoint me. We were outside for around 8 to 9 hours. Again, I would recommend Merrell shoes and boots to anyone.
Wore these for 7 days straight during my trip to Mongolia were temperatures were down to 10°F. . My feet were warm, but never over heated. I also have very wide feet and never suffered any pain from my toes being push together. I will keep this boot as my outdoor boot for as long as it is available.
My Merrell Moab 3 Thermo Mid Waterproof Wide Width boots fit at though they were custom made for me.right out of the box. This and other pairs of Merrell sneakers and boots fit as though I have been wearing them before I unboxed them. I use wide pairs to accomodate my bunions which have more room. I love Merrell footware and will always order them because of their special personal fit from they time they are brand new.
I got these boots as a Christmas gift for my husband. He is over the moon about these! When he put them on he said “I can’t believe the tongue is even padded. These are so comfortable!” The next day, we took the dog for a walk and he wore the boots. He couldn’t stop going off about how much he loves these! “I can’t believe how comfortable these boots are, and I’ve never heard of this brand!” Highly recommend these :)
Only get them if you have skinny feet. These are my 6th pair of Merrell shoes, and I've never had a problem, always a fantastic experience. However, these shoes are excruciatingly painful because they're so narrow. I actually have growth on the sides of my feet because of these shoes. They weren't exactly cheap, and now I have to find something else. I just hope my feet go back to normal.
Not quite what I expected. The shoe doesn't really snug up to my ankle the way I would prefer. It's a bit stiff around the top that sometimes rubs against my leg. Probably should have stayed with a full size boot. I would have preferred more insulation as they are not quite warm enough for me. I tried them and will wear them until they wear out, but most likely would not buy again.
15k walk straight out of the box , perfect. Normally size 9 regular, got a 9 wide , so I would suggest this boot runs slightly narrow. Very soft for a new leather boot , the foot bed is comfortable. Temperature was around 8c and with good socks I got a bit warm so would not use much above 10c … it is a thermal! Let’s see how they perform in the brutal Winnipeg winter.
Perfect for cold weather hiking. Good insulation in both the upper and the sole. True to size. I wear a size 11 running shoe in almost any brand. My foot is wide in the forefoot but otherwise not wide or high volume. I got size 11 and it accommodates heavy winter socks. So you don't have to go a size up for thick socks versus what you wear in the summer.
Beautiful boots, color exactly as shown on the website. Very comfortable & warm, no thick socks needed with these! True to size. Firm, yet comfortable arch support. Solid construction, light compared to the steel toe boots I'm used to. Footing feels secure, traction is excellent & non-slip. These boots are built to last. Very satisfied with my purchase!
