Merrell Siren 3 Mid GTX, Women's High Rise Hiking Boots

[Update Jan 2021] I know this review is getting a bit long to read, but it's based on several years of use by myself and my wife of these boots and hopefully helpful for what is an important and relatively costly purchase. Thx. Just wanted to add that whilst these boots are great in most conditions, they do not have a very deep cut sole. It's good quality but in muddy conditions can clog quickly. Had this yesterday on a muddy chalky walk where I ended up tumbling a couple of times. I'm usually steady on my feet and to be fair I don't know that boots with a deeper cut sole would have been any better. There were lots of marks on the track where others were having the same issue. Would also like to comment on the reviews that say these are not waterproof. I can say categorically after years wearing them and walking through streams, that they ARE. If someone gets a pair that are not, just get them replaced. It's a fault with that pair not the design or materials. I had a pair replaced by Merrell after they split (I think on a rock) and this damaged the Goretex. It's also worth saying that waterproof boots (or clothes) can still feel wet. If the outer is soaking wet you'll still feel some cold and damp even if no water has actually gotten in. It can feel like socks are damp (my wife notices more than me). Try with a piece of tissue inside to check whether they are actually leaking or not. We only notice this if wading or walking though long wet grass (i.e. not really in rain). It's still worth having because a) it's a short damp feeling and b) the outer will dry out quicker than if the inner and your stock was soaked. [Update November 2021] My wife has continued to use these boots for our walks near home and last year for a few months in France (waterproofing not really required for either). We’ve just got back from a week in the Lakes where we did a lot of walking on flooded paths, bogs and the usual quite stony terrain etc. Both her and my boots stayed dry throughout (we do usually wear waterproof gaiters covering part of the upper), but that’s to protect trousers from mud rather than because the boots need it. Both her and my boots remain comfortable and are mostly holding up well (soles linings etc). My wife uses custom insoles, but I have the standard Merrell in (despite having used more supportive insoles in other boots). The only additional negative I’ll add is that the trim on the uppers (I.e the leather-look strappy bits over the mesh) has not held up well. The upper surface has just flaked and peeled off on hers. Seems to happen when cleaning (even if just sprayed with a hose). Unsightly, but does not affect performance. [Update: Dec 2018. Were managing to get at least one walk in a week since buying these averaging 6-9 miles now. Both of us find the boots supremely comfortable. My wife had some minor pressure under one toe on an 11 mile walk, but nothing major. We've not been out in downpours but wet grass and the odd stream splash has not been an issue. I would add to my review below that the soles are good and grippy in most conditions, but not as stiff as a heavier boot, so you will feel a rocky surface through them slightly. Not a problem, just trying to give a better impression of what these are. We have not done any walking with more than a day sack so far and only short easy scrambles.] Bought for my wife after I bought a men's pair. Both of us found the boots comfortable out of the box. My wife has quite a wide forefoot and a bunion on one foot, but no problems so far. I bought mine after having to give up walking for a while because I developed an issue with my heel rubbing in my (well-known major brand name) leather boots meaning I had to pre-pad or put Compeed on after about a mile on the trail. I spent ages travelling to specialists (Alt-Berg/George Fisher) trying to get a solution. Different lacing, socks, insoles did not help. I tried all the boots I could in store but no one could tell me whether or not I'd be OK with them. Rather than wasting a pot of cash on boots like that, I went for these as they were a little bit less of a financial disaster if they were no good. Glad I did as I've had no problem with the heel in these. We've just got back from a few days in the Lakes where we used them everyday for moderate walks over mixed ground including some rocky sections. Did a great job. I developed a slight pressure on one little toe towards the end of an 8 mile walk on which I'd done some sections as fast as I could over all terrains. I'd say that's not bad at all. My wife mentioned some damp feeling on one boot after crossing a shallow stream, but we're not sure yet if there was any leak of if this was just the damp cold feeling you can get with most Goretex when the outer gets wetted out. Being a fabric/mesh I suppose this is more likely to happen quicker than a well-treated leather. There doesn't seem to be any kind of DWR on the outer on these. But there's always the Gore-tex guarantee to lean on if needed. We both found the soles made crossing rocky sections quite comfortable, easy and fast. So far so good - will update if any issues (I do actually update my reviews if things change ratehr than just say it :-) ).

I bought these walking boots initially for the cotswolds way that we will be walking in August. I went for comfort rather than water proofing as over the years I have had many different types makes and models of boots and they have all let in a certain amount of water. I have just been on my first walk in them it was 6 miles of bog, mud and water, my feet were completely dry when I took them off at home so have to say THEY ARE WATER PROOF despite some of the reviews I have read. I am a size 7 foot but had to send the first ones back as slightly too small. I then ordered a 7.5 which is a perfect fit plenty of room. Delivery was prompt and on schedule. So when ordering I would suggest getting a size bigger. The boot itself is lightweight compared to some other brand. But when on appear to be strong, sturdy and provides foot and ankles with good support and structure. Very comfortable. Update 11/05/25 Have owned these boot for last two years during it's time I have walked the cotswolds way and hadrians wall walk. These boots are so comfortable I have not had a single blister And they are still going strong planning to do the ridgeway in august. The boots have only let in water 3 times and this was when walking in rain that has lasted 3 to 6 hours at a time, the bonus of them being light weight is that they dry off really quickly and are ready to use the next day. Best buy yet for walking boot.

I have the worlds most difficult feet. They are wiiiiiiide, and flat with narrow heels. A bit like a duck. So good walking shoes are not easy to come by. I hadn't tried Merrel before having tried some on a few times with no luck. But this time I was after a lighter weight pair of walking boots that i could wear around town but also get away with a major hike in fair conditions. They aren't waterproof, but are really good boots. Very comfy. I ummed and arred over the fitting and went for a half size bigger in the end. I'm glad i did. Love them, would buy again. Happy for them to wear out at this price. EDIT: I'm adding this extra note after purchasing a second pair. They don't last very long so don't pay too much for them. And they are only waterproof a bit at the start, but wear soon looses this (even with waterproofing and good treatment). I bought a second pair as i find it hard to get boots that fit well and they are good, but one of the lace loops broke after just a couple of months (Amazon refunded some of the cost, thanks) so be aware of poor manufacturing.

These a such great boots. Waterproof, great grips (even in slippery & icy patches) and so lightweight that I barely feel them on. True to size and a nice leather so look stylish and are very comfy. Super glad to have bought them - worth every penny of cost.

These had their first outing yesterday on quick 5 mile forest hike. They were super comfy right from the off with plenty of room in the toe box and a sung fit around the ankles and heel. I did apply nikwax before I used them to offer extra protection knowing that the tracks would be very muddy after days of rain. They were perfect, my feet stayed dry and cosy throughout, this is my second pair of Merrell hiking boots, I use my others for summer walking and they are both superb. The vibram sole meant that I had excellent grip on slippy and uneven terrain and whilst I was not walking through rivers I did ford some streams and they performed beautifully. I have very narrow ankles and heels and the padding in these sections meant that there was no rubbing. Amazing boots!!!

I've had these shoes for 4 years now and absolutely love them. I was looking for a light and versatile multi season walking boot. I've done week long alpine treks in them, climbed Scottish mountains and even enjoyed pounding them around town. Never had a blister and never have that feeling of 'get me out of these boots!'. Unfortunately they are no longer as waterproof as they were, but given all the use I've got out of them I won't hesitate in buying another pair.

Comfortable, well cushioned and ample of space in e shoes, suitable for ppl with wide feet. Don’t even need to break in.

Bonitos tardan unas tres semanas en llegar porque me dicen que vienen de Israel.

I went to the Roan Highlands in NC last month with my Merrell Blaze Aeros which are great water hiking shoes but failed at rocky mountain hikes because my ankles were rolling and twisting like crazy so I knew I needed more support. I got some Columbias but they were stiff and just didnt feel right. These Merrels matched the color and style of my Blaze so I took the plunge and got them. I literally could not shut up about these boots the entire hike. As you can see, my boyfriend was wearing sneakers and I had to walk ahead of him to let him know when something was muddy or wet, he was not a happy camper (literally) and I will be getting him some Merrells for our next hike. I did 2 days and about 15 miles on the Blue Ridge mountains, completed the Sam Knob mountain and Flat Laurel creek trails so these boots saw it all. This trail had lots of mud, rocks, climbs, and water. These boots took it all like a champ including fully submerging them in mud and creeks and they stayed completely dry and look brand new, I was absolutely blown away. The inserts are a bit too thin and tough for my taste so I replaced them with some Vomii memory foam insoles and it was the bees knees. The support is there, the grip is there, the style is there and they are comfy right out of the box. By the end of the hike my ankle did hurt a little but that's normal when breaking in new boots, especially when hiking such uneven and rocky terrain. I normally wear a 9-9.5 but I listened to the reviews and got a 10 and I'm glad I did because anything smaller would have been tight especially around the toe box especially because I wear them with thick Darn Tough socks. I love these boots so much I couldn't stop raving about them and said the first thing I would do when I got back home was write a review on them. Thank you Merrell for making the best hiking boots ever and best of all, they cost way less than the Salewas I was going to get.

Chaussures de qualité, agréables à porter.

It is indeed water proof, at least when I walked in the snow, I don't feel melted water penetrate inside the shoes. I felt a little bit painful for my back heel in the first two times when I wore it, but once I got used to it, it's super. Very wide in the forefeet place and very comfortable even with a lot of walk.
