Customer Reviews Merrell Agility Synthesis Flex

Would buy again

Size 15 M fits great, even though I tend to wear wide shoes, very happy, great job again Merrell.

this is my 3rd pair of Merrell shoes or boots. Incredibly light but still feel supportive. Like being barefoot with an armored sole. Love the shoe.

This is my second pair of Merrill Agility Synthesis Flex. I like the fit and the look. I use them primarily for walking .. both on paved trails and wooded trails... However, they look good and are suitable for casual wear. The Agility Synthesis Flex shoes are comfortable and supply good support during walking , jogging and hiking.

This is my second pair of these shoes. I am wearing one pair at work and the other for casual wear. They are very comfortable, have good cushioning and look good too!

Great, comfortable shoe! Appears very durable.

I disc golf a lot and walk my dog a minimum of 2 miles every day. This shoe fits and supports those activities extremely well. It's comfortable and absorbs impacts, Its light and resisted water on a wet disc golf course. What I love the most is the traction I get on steep, muddy hills & ravines. It's the perfect shoe for what I need. So much I just bought a second pair.

This trail running shoe has the best fit and feel of any shoe that I have ever tried in this category in any brand. Somehow the material used in this shoe allows for no pressure points, flexibility in all the right areas without any compromises. The tread is ideal for hard packed surfaces and lose to muddy/wet surfaces. The tread is fairly "soft" and will wear fairly quick if you use this shoe to run on paved surfaces. But, who wants to run on pavement? Find a trail and enjoy this shoe, I dare you!

Very comfortable solid feel. The first time I wore these shoes for about eight hours and they felt the same all day, great. Good traction and snug fit. Would buy again. I can't say how they'll hold up for the long haul but I'm hoping for the best.

Merrell did it again! I absolutely love your shoes. Fit the comfort everything is just perfect. These shoes I absolutely love. They're comfortable the fit is perfect right out of the box. I bought a pair three months ago and I'm going to buy another pair.

The one thing I can always count on with Merrell is consistent fit. I take a size 11.5 medium and these Agility Flex shoes fit great. They are also light and that is a plus when wearing all day.

Fit as expected, right out of the box. Very light, very comfortable. I walk about 5 miles a day, 2 to 3 of them were in the shoe. Nice shoe

Lobe these shoes

I needed a pair of trail runners at the last minute for an upcoming obstacle/trail race. These performed extremely well. There was over a thousand feet of elevation change on the course, and it had just rained, so there was a fair amount of mud. The grip on these shoes never failed. There was no slipping on the uphill sections, and the forward leaning lugs on the heal gave me an incredible amount of confidence on the downhill sections. Over the flat portions of the race, they provided firm and comfortable footing through mud, gravel, rocks, etc. They were also good to go right out of the box. The race was the first chance that I really had to wear them and my feet felt fine afterwards. They also fit exactly to my size which is important whenever you order something online. They are extremely light (which is a plus), but if I had to say anything negative about them, it would be that they tend to be slightly loose around the heal on me. I've used Merrell before for hiking shoes, but always went with more established running shoe brands for my trail runners. These were an extremely pleasant surprise. Well done.

Great shoe. On my feet all day on concrete and they reduce stress and fatigue. Only minus is the toe box seems to be very large.

I have lifted weights, run, walk volleyball, etc. I have yet to take them on a trail as it is really cold. They have been great for all of those activities. They have great traction and can't imagine anything less then that on the trail. I get a ton of compliments since they don't look like everyday boring sneakers.

As a Merrell ambassador, I've had early access to this model and I've been in love my my Agility Synthesis Flex since the beginning. My ASF's have climbed Long's Peak via the keyhole Ridge Route(5.6), Been part of the Grand Teton Triathlon summiting the Grand and run the Tahoe 200 Mile Endurance Race. I also used these shoes to complete the running portion of the Rainier Infinity Loop. This is currently my go-to trail runner. The upper is very soft, which is how I like my trail runners. The sole is grippy enough to tackle rock climbing routes up through 5.6 in difficulty and take on long distance races. The toe box was a little narrow for distances after 100 miles and I'll need to upsize or select a wider toebox model for another race of that distance.

I've been dealing with foot/toe pain that has caused me to seek out shoes that provide good comfort, support and fit while not hurting my big toe...and these shoes feel GREAT. Lightweight and well-made. Love them...and funky colors are a bonus.

Im a true size 14 with a fairly narrow foot and this shoe fits well with room in the toe box while running trails. I found the arch to not have quite enough support for my mild pronation and have added a small insert/ arch support. Thus far, I'd purchase this shoe again.

This is by far one of my favorite trail runners yet by Merrell. The Agility Synthesis Flex not only provides the support and comfort needed for the trails, but it also keeps you firm footed for every type of terrain you come across. As a Merrell ambassador, I take these shoes on almost every adventure on the trails. The upper is fantastic, reliable breathability, and doesn't allow any sort of dust or sand coming through the shoes. So you'll end up with clean feet at the end of an adventure. The only down side is the toe box could be a little wider, even when you're fitted with the extra length as needed. Overall, this is one of the best shoes I've worn by Merrell.

As a Merrell Ambassador, I have had the opportunity to try many Merrell products and this shoe is my favorite running shoe on ALL surfaces. This shoe is light weight, provides adequate support for all distances and is breathable. I first thought I would use this shoe for trail running only but one day I decided to hit the road with these and now they are simply my running shoes no matter what I am running on.

Have a great look, perfect fit and lite weight. I ordered three different pairs of shoes from different companies and this was the only pair I did not return.

I love Merrell shoes. Merrell 15's are all I get. They always fit. Thanks for making big shoes!!

I have only had these shoes a short time but I expect to get long life and comfort for the life of these shoes. They provide a good fit and sturdy build.
