Why We Like The Merrell Siren 4 Hiking Shoe

The Siren 4 Hiking Shoe gives us a women's-specific fit and Merrell comfort. The breathable mesh uppers keep things light on our feet while the cushy foam midsoles soften each step as the miles pile up. When the trail gets tougher, the rock plate gives us some mid-foot protection, and the deep, 5mm lugs help us dig into the Earth for secure footing.


  • Hiking shoe that cradles women's feet
  • FloatPro Foam midsoles give us lightweight cushioning
  • PU footbed is removable and treated for odor-causing bacteria
  • Vibram outsole offers all-terrain traction
  • 8mm drop
  • Recycled materials in lining, laces, webbing to reduce waste
  • Item #MERZ2SJ

Love these shoes!

I have problem feet and have for years. Basically I’m flat footed and have bunions on both feet. Shoes with too high of an arch built in cut into my foot and throw my foot off to the opposite side of the shoe. These have just enough of an arch to give me support and also are just wide enough to float over my bunions, never irritating them. I have all colors of these.

Hurts my right ankle

I’ve been wearing Siren Sport 2 then 3 for many years. I was very excited to see Siren 4 because they look so pretty. I purchased a pair, but had to return. Although it feels very comfortable, the back of the right one was too high and it hurts my right ankle. Eventually, I found a 3 somewhere else. Would you please make a Siren that is as comfortable as 3 and as pretty as 4?

Hot footwear

After owning four pairs of Merrill, shoes, I found this pair online and purchased for a vacation to the beach. I took my first walk around five km, and found the foot bed to have minimal support. The rubberized base and toe cap, did not allow for ventilation making the footwear extremely hot. The shoes look great as all Merrill, footwear.

OK, but no more

True to size, ok for thin feet, quite heavy to use in a multisport way

Try them on in person if you can

Love the colors, love the grip They fit large though. I checked other merrells and their size guide which suggested 8 or 8.5. I got a 7.5 as I am normally a 7 but the guide suggested a full size larger. They are too big.

Siren line this is not

I've been wearing the Siren Sport line since 2012. After being unable to find my usual Siren Sport 3 listing, I found these. I was eager to try out the new insoles included as since the OrthoLite Comfort Foam has stopped being carried, I've needed to get insoles elsewhere. Upon opening the box, I noticed they looked very narrow. When I went to try them on, there was no way my foot was getting in them. Apparently these don't come in a wider width so I can't try that. Luckily, the day after I purchased these, I received an email to review the Siren Sport 3 and was able to purchase my size. Put my new 3s on after trying these and whadda ya know? Perfect fit.

Painful and slippery

I bought the Siren 4 shoe about 2 weeks ago and was only able to wear them once. There must be a defect with the shoe as the right shoe has what appears to be a wire that sticks out under the collar and digs in to my right ankle. It was very painful, so I could not wear them for very long. They also have no grip. In the short amount of time that I wore them I fell twice due to the slippery sole. I own The North Face shoes and have used them for hiking many times without any issues. I will stick to that brand from Now on. I called Merrell about the problem with the shoes and unfortunately they won’t issue a refund.

Pretty shoes

Bought these and have been wearing. They definitely run BIG. Gonna size down 1/2 size and give the larger ones away. Been wearing Sirens for years, first time I ever had a sizing issue. Merrell needs to upgrade their quality department apparently…

Sizing Issue

Not sure if got pair incorrectly labelled re: size as fit at least 1/2 size larger than Siren 3. Tread is great and sole is soft and comfy, however, collar of shoe is not well padded and quite stiff. Shoe has a nice look.
