Rated 2 out of 5 by Maggie0623 Too small. Love Merrells.
I purchased these hiking boots along with the Ascender Gore-Tex. I have purchased Merrells in the past & have never had an issue with the fit, unfortunately these in a size 9 are too small and too narrow. The Ascenders fit and are very comfortable. I look forward to using them on our upcoming trip to Glacier National Park. I will be returning the Merrells for refund.

Rated 4 out of 5 by OutdoorsAllDay Excellent in many ways but...
The most important advice I can give re this shoe is to order at least a half size up, if not a whole size. I followed the advice of reviewers when I made my order and went from my normal size 9 to a 9 1/2. It was too short. I exchanged them for a 10 which was perfect. Held sole to sole with one of my (size 9) running shoes, they looked the same. I normally take a medium width, and I had no problem with medium in any of the pairs I tried. I give them four stars because they are very comfortable to walk in, but I almost gave them three because it took some breaking in before the outside edges didn't gouge the underside of my ankles. (I had a friend who solved this kind of problem by adding insoles.) And as to the waterproof quality, it's odd - I stepped accidentally into a puddle that covered the top of the shoe - and my foot stayed dry, but a couple of minutes of walking in wet grass soaks my toes - every time. I'm keeping them because they are very comfortable, I like the subtle coloring and because I've gotten used to, or broken in the shoes to solve, the gouged-ankle problem.

Rated 5 out of 5 by GrannyHikerOne Comfortable, good grip on trails, breathe well!
I liked these shoes so much that this is my second pair! I wear them all year round as my every day shoe, not just for hiking. I am grateful that the sizing runs on the small size because my feet are a size 5 1/2, and it is so difficult to find a shoe that actually fits.

Rated 2 out of 5 by 1000shoes waterproof? where?
Wearing the Merrell Siren Sport 2 Waterproof Hiker my feet stay comfortably wet every morning I wear them. In north Mississippi the dew is heavy nine months out of the year, so I can look forward to wet feet from now until late October. I remove them immediately after walking, remove the insole and place them to dry. After just nine hours (nine mornings) of wear they began to have a strange acrid smell.
I ordered them because they were described as "waterproof" It is true that the synthetic leather stays dry everything else holds water like a sponge. Some mornings they still have not dried from the previous morning. I realize that if I continue placing them in the sun to dry the fiber will break down prematurely.
This shoe fails to do what I need it to do.

Rated 3 out of 5 by JustAnotherReviewer Very narrow with extremely firm soles
If your feet are even just a bit on the wide side I would not recommend purchasing these particular shoes. They are very narrow. Also the sole if very firm and does not flex easily. I've only worn mine for about 5 hours, so I'm not sure if they will 'give' any as time goes by. Other than that the shoes appear to be well constructed.

Rated 5 out of 5 by AvidHikerandCamper Heed the warning about sizing
My last pair of Merrell Sirens were an 8, so that is what I ordered. Had to trade them in for an 81/2. Once I did that, though, I put them on and took a 3 mile walk over wet, rooty and rocky terrain. They were comfy from the start and stayed dry the entire 3 miles. Love Merrells. I have a wide forefoot but a narrow heel and Merrell always fits me comfortably and they hold up well to my hard use.

Rated 3 out of 5 by GeoMom Heed the warnings
After reading the other reviews, I ordered a half size up from normal. I would have ordered a wide width, unfortunately that option does not exist. The shoe was uncomfortably small both in length and width with just a thin dress sock, and I could not possibly have gotten a mid weight hiking sock on. I sent them back.

Rated 5 out of 5 by nadeaumidd Good item
I love the style. Very sturdy with an excellent tread. As stated before though, definitely order a half-size up. I normally wear a size 7 and my toes were touching the end of the shoe and they were uncomfortably tight width-wise. A 71/2 was perfect.

Rated 1 out of 5 by greatguy Squeaky Soles!
These fit very well but the soles made terrific noise when i was walking on hard surfaces. Now, bought my husband a different pair of Merrells AllOut Blaze shoes and no squeaks. The squeaking may not bother everyone, but even my hard-of-hearing husband heard them.

Rated 4 out of 5 by Plantnut Nice Hiker - but questionable water resistance
Definitely order 1/2 size larger than you normally wear since the shoe runs a little small. Very comfortable and well built. Unfortunately, I cannot say that they are completely waterproof. Had leak-through recently and will be exchanging shoe for a different style. Possibly only Goretex is truly waterproof. Next pair of hikers will have Goretex.
