A Siren that responds to the urge to surge. But with a full grain leather upper and rubber bumpers at toe and heel it is built for durability. Merrell Air Cushion midsole with women-specific Q-Form technology smoothes out strides while maintaining alignment. Vibram Siren sole features heavier lug pattern in high-friction areas and tread for vital traction under the arch.
Very comfortable shoes
I don't like my feet to get hot while I walk trails and these shoes keep my feet comfortably cool while also giving me excellent traction/footing.
They're comfortable right out of the box with no break-in time.
An added bonus is that they are also attractive! (I purchased them in espresso.)
Awesome!
This is my third pair of this particular model of shoes by Merrell. I wear them every day walking/running my dogs. In my opinion Merrell makes the best shoes for my feet. I just love them and hope they become a classic and they never stop making them. They fit great, are light but sturdy, and well made. I've gotten them soaking wet, and they dry and you would never know it.
Great Work Shoe
I'm a veterinarian stringing together 10-12 hr days on my feet. Since I purchased these shoes my legs and feet have been comfy and pain free. As an added bonus, the shoes are cute and coordinate with almost any scrub color. I will definitely purchase again...if they ever wear out!

Merrell Shoes for women
I love my Merrell shoes. I work in a hospital and I could not make it without them. I noticed the doctor's would wear them. I use to wear Reebok walkers but after four years of Merrell's there's no going back. I'm 52 years old. I love the stability and fit, not to mention the durability. Keep up the quality.
My first Merrell shoe
Several of my friends have Merrell's and they recommended I try a pair. I love them!! They are the most comfortable shoe I've ever worn. I will purchase many more pairs in the future.
Fantastic shoe!
These are seriously the most comfortable, high-quality shoes I have ever worn. I wore them on a month-long trip across Europe in January-February and they performed wonderfully. We walked on average 8 miles a day, and they were comfortable, supportive, tractioned, and water resistant every step of the way. Great roomy toe box, yet snug enough to fit my narrow feet. I've worn them nonstop since January and they show no wear. I'll never go back to regular sneakers.
Great Shoe
I have been wearing merrell shoes for 3 years as I have a high arch and it fits me best.
great
wonderful shoe. My feet, ankles and knees feel so supported. Best shoe I have worn in a long time
Cross Trainer
This Merrell cross trainer is unbelievably confortable. I have a high arch and I need wiggly room for my toes and this shoe gives me both. I love them and have received many compliments. Love this shoe!
Great shoe!
These are the best athletic shoes I've ever owned. They are cute and comfortable. Once you try these, you'll be hooked! I try on other shoes, but I always end up buying Merrells because nothing's better! With these, I got 1/2 size larger than what I normally wear.
Finally a good pair to run anywhere
Occasionally I run in asphalt, and these babies run by themselves, no impact on heels or aching knees. The women-specific Q-form sole makes them an asset.
excellent fit and comfort
This is the first pair of shoes I can wear all day without foot fatigue. I walk every day for an hour with my dog and these provide superb fit and cushion even when running. Highly recommended!
Plan on buying more pairs
Most comfortable running shoe I've ever owned. All I had to do was put them on and start running. No blisters, my feet aren't sore and they didn't need any breaking in. My first pair of Merrells, and I definitely will buy another pair.
These are the Best!
These are the most comfortable, best fitting shoes I have ever worn. My daughter, who is very hard to fit, tried these on and has finally found a shoe she can wear for long periods of time without discomfort
I love my Merrells
This is my third pair of Merrells and I just love them.
The fit is great, the light weight of the Siren Sport shoe is just perfect.
Look great!
I haven't had much experience in them, but the 15 miles or so that I've put into them, I'm enjoying every minute of it. The heel is what makes it or breaks it for me... it's really comfortable and fits tight. No blisters and no movement make this a very exciting shoe for me.
Really Great Shoe except for one thing
I have 4 pairs of these. I have narrow feet and wear orthotics. I wear them all the time and for walking, hiking, trail running...... The only thing is that the heel wears out way too fast. It is supposed to be a vibram sole, but there seems to be a different material right at the heel where you wear it out the most.
I do recommend the shoes. Just put shoe goo on the heel.
Merrell Shoe
These are great shoes. Very comfortable and stylish. The only problem I have is that they seem to run a bit large. I am returning them for a half size smaller. I plan to wear these shoes to Costa Rica on my honeymoon.
So far, excellent
Bought these to wear as my everything shoe for an upcoming trip - want them to wear for everyday treks through city streets and for hiking and thought I should test them out and break them in, in advance.
So far, they are exceedingly comfortable. I do have a rather wide instep, and I notice that there is just a little rubbing on the outside of my foot from the place where the strapping that keeps the laces in place is stitched. It is the only location on the whole of the shoe where there is a seam on the inside, and it is thin, but I have to keep the lacing at that point very loose to avoid rubbing.
But otherwise this is the first shoe I have ever purchased that felt this good out of the box. They are very light-weight, have a great sole and they do as they claim by compensating for natural pronation.
a little puffier than I expected
Overall very comfy--like a sneaker combined with a hiking shoe. I like them overall.
