Lightweight wading boots with RiverTread platforms and CleanStream design for wet trails and all-day wading.

The Simms Men's G3 Guide Boot provides a lighter weight with more durability for wet trails and all-day wading (as compared to the signature Guide Boot). Its waterproof nubuck leather and TPU-coated textile uppers offer protection, durability, and abrasion resistance while you wade, hike down a steep ravine to the water's edge, or bushwack through the woods to your secret spot on the river. Partial neoprene lining provides wading warmth, cushioning, and an easy on-and-off while the G3's traditional lacing helps ensure a just-right performance fit. Simms also gave the G3 a CleanStream design which includes features and materials (less exposed stitching, fewer ridges, non-absorbent materials) that are more resistant to hitchhiking organisms—all to make the boots easier to inspect, clean, and dry faster.  

Designed with Simms RiverTread platforms, the G3 delivers maximum comfort, performance, and slip-resistance so you can concentrate on making that perfect cast. In addition, the RiverTread is both trail-ready and wading-ready, thanks to its molded 3D footbed with arch support and ball flex that align your foot for all-day comfort and optimal bio-mechanics. The molded dual-density EVA midsole provides cushioning for hiking comfort enhanced proprioception. Simms also equipped the RiverTread platform with molded, minimal, and hidden TPU retention plates for lightweight cleat retention and enhanced proprioception. And for long-lasting traction on trails, slip-resistance in water, and toe protection you can rely on, the G3 has a molded Vibram Idogrib rubber outsole with 4-millimeters of self-sharpening, multi-directional lugs.

All grown up now

    After 25 years of fly fishing I finally decided to break down and get big boy gear so I gave away my neoprene waders with the permanent rubber boots and bought these to go with the new waders I just bought. I should have done this 24 years ago. They come sized with wader booties in mind so you should buy the same size as your normal shoe size however, I am dealing with a swollen foot full of metal and screws so I wanted a little extra room in case they rubbed. Worked out that they were more comfortable on the surgically repaired appendage than the good one but that evened out once they were filled with water and I moved around a bit. They were VERY comfortable and even though they seemed quite rigid, I had no difficulty sensing the terrain in the bottom of the river holes. The hard strap on the back is nice for helping pull them on so you don’t have to totally unlace to get them on and the lug soles worked just fine on the rocks and trees I had to deal with. They also laced up very nicely so I didn’t have to deal with a bunch of silt in them that I had to wade through. Since this is my first pair I don’t have much to compare too but my fishing buddy liked them much better than any of the brands or styles he has owned in the past

    Best wading boots I have used

    • Familiarity: I've used it several times

    This is my second pair of Simms G3 Guide Boots.
    I tried several other brands and styles of boots before buying my first pair of Simms G3 Guide Boots. That pair lasted for 5 or 6 years and at least 400 days on the water in extremely rocky substrate. I went through 2 sets of studs and finally the outsoles were worn to the point that the tread was nearly gone.
    For my money, I wouldn't buy anything else.


    • Familiarity: I've used it several times

    Simms makes the best quality wading boot out there. I beat my boots up pretty good-fish a ton of small creeks and put a lot of miles on hiking in them. Their boots last way longer than any other ones me or my dad have tried, and I've tried quite a few! I've had some cheaper ones last only a few days in rugged terrain. Once I found these I was hooked. I Never buy any other brand anymore

    You're Gonna Like It

    • Familiarity: I've put it through the wringer

    Awesome boots. These are my first fly fishing boots and I'm glad I spent a little extra money to ensure they would be everything I would need for year round and all day use. The high ankle is awesome for rocker/deeper areas. On top of that, it's tough to argue against Simms lifetime warranty!


    • Familiarity: I've used it several times

    What an Upgrade, was using a really old worn out pair of Simms handed down from my dad. These are amazing. I can hike all day in them and not have sore feet. In and out of the water these make those all day fishing adventures that much better. High ankle helps with walking through boulders in the river and my feet have stayed much warmer than my old pair of wading boots.

    Awesome boot, on my 3rd pair

    • Familiarity: I gave it as a gift but have feedback to share

    Gave to my dad, here's his feedback:

    Awesome boots, have been my go to for years! I'm on my 3rd pair, as I keep wearing them out! Keep my feet warm in those cold northern Utah streams. I'll probably keep getting them unless they stop making them! Nothing bad to say.

    Killer boots man

    • Familiarity: I've put it through the wringer

    The Simms G3 Guide Boot is like walking on a cloud. This super burly boot will hold up in the worst conditions and outlast any other boot. The classic lace system is extremely durable and long lasting and allows you to dial in the fit and tighten areas separate from each other. Also the high cuff gives you extra support on those hard river crossings while providing all day comfort. I have spent many hours, days, and weeks on the river in these puppies and they are still as perfect as the day I got them. The sizing of these boots are spot on. I got one size bigger than my normal shoe size and it fit perfect. I paired these boots with the Redington Sonic-Pro Wader and they fit impeccably. I would recommend these boots to anyone looking for a super burly boot with all day comfort. Whether it’s snowing out or a brisk summer morning, these boots are the perfect choice and will always be in my pack on all my fishing trips.If you have any questions hit me at 801-523-4075 or email me at

    You Get What you Pay For

    • Familiarity: I've put it through the wringer

    The BEST wading boots I have ever put on my feet. Well worth the extra cash to get something that will last forever, and will perform day after day. I would recommend buying the SAME size street shoe that you wear. There is some extra room for waders. Get you some and see what the hype is all about.

    If Only all Gear Performed like these

    • Familiarity: I've put it through the wringer

    Whether you are a weekend warrior or an everyday guide these boots are the ticket. Very comfortable, give feet that extra bit of warmth when in freezing waters, and will last and last. These are the boots I wear year round and have been for the past 3 years. They are still in amazing condition. Make sure to size up to fit those thick socks and waders or booties inside.


      Super good feeling and looking boot for the river. It is very comfortable for those long hikes to the honey hole and supportive for getting down or up steep banks. I only give them 4 stars because they are VERY slick in the water. Save your tailbone and get some cleats for these boots

      Nothing better out there!

      • Familiarity: I've put it through the wringer

      I waited a little to write a review for these bad boys and I am glad I did. I have absolutely hammered these boots in the past two months and they look the same as the first day I put them on. I love them to death. They fit pretty true to size in terms of wading boots. I wear a size 9 shoe and am rocking this in a size 9 and they fit great. They are a little on the heavy side but when you feel how durable and strong they are, its not an issue. They give me confidence to go where I want to and spend long ours on the river. A must have if you are hard on gear and are looking for something that will last years to come.

      Simms Does It Again

      • Familiarity: I've put it through the wringer

      I have the previous version of this boot, but due a careless thawing incident involving frozen boots, I warped one of them causing some discomfort on one foot. I decided to pony up the money to replace them and I didn't expect the new version to be much better.

      I was quite wrong. Simms really have improved the G3 Guide boot. There is more volume in the boot I've found, which might be a bonus in winter time. Although there is more volume, I didn't have any issues with my feet being loose and my heals feel better locked in place than the previous pair. With the reinforcements, I think these are more bomber than before too.

      On a recent trip to Montana and Colorado, my feet never got tired, even on days we were on our feet for 10 and half hours straight...


      • Familiarity: I've put it through the wringer

      If you're the occasional angler you can get away with spending a little less on wading gear. But if you're out there all the time, it pays to spend the extra money and get quality.
      The G# guide boots are meant to take a beating and last forever. They're a burly boot that's overbuilt to withstand countless hours submerged, miles of hiking (though certainly not a hiking oriented wading boot), and stumbling through rocks and thick brush.
      They are extremely supportive with a pretty stiff upper and an extra high cuff that saves your ankle when you inevitably roll over river rocks.
      What's nice about these is the fact that the soles seems very malleable. Your foot can conform to shape of whatever you're walking on. Lots of times with wading boots, it can seem like you're on a very stiff soled platorm, but no so with these. I think that really helps with grip in slippery situations.
      One last thing I'll point out is the big tab on the heel is super helpful when pulling on these boots. Sometimes with wading booties it can be tricky to get wading boots on or off, but this feature is great.

      Tractors on your feet

      • Familiarity: I've put it through the wringer

      Have worn these inside and out for the past year guiding and hiking throughout all of Colorado and Utah. The boots offer superior protection with the high top support and offer that sleek, stylish look with the leather wrapping.

      Since the boot is also lined with a slick neoprene like material, it is easy to get in and out of your waders with the back pull tab of the boot.

      The rubber vibram soles are super comfy and keep those invasive species from traveling stream to stream. If you find them too slippery, Simms studs are easily attached

      Tractors on your feet

      If you fish a lot, buy these!

      • Familiarity: I've put it through the wringer

      Being that these wading boots are $200, they may not be for everybody, but if you fish just about every chance you get, these are the boots for you hands down. These boots are seem to be super durable being that they are made with waterproof leather (so they don't shrink like the old version did with normal leather) and a solid vibram sole. The new RiverTread sole is amazing. It grips on everything (I have never put cleats in them and have never felt like I needed to), they're super comfortable when your walking, and have just the amount of softness so you can feel what is underfoot but still support your foot on uneven surfaces. The whole Proprioception thing sounds like a gimic, but it honestly lets your foot feel what is underneath it so that you can grip rocks and know what you are standing on, but the sole is still stiff enough overall to support your foot on uneven surfaces in the river and feel comfortable while hiking. I love how high the boot is and it gives you great ankle stability. Also, when walking this boot feels like a pillow on your foot, I don't think I've ever owned a boot that was so comfortable. I'd honestly like to say there was a drawback to these boots to provide an honest review, but I honestly can't think of one. If you don't want to spend quite this much money on a pair of wading boots, check out the Simms Freestone boots. They are great boots also but cost about $50 less.

      Rock solid & Comfortable

      • Familiarity: I've put it through the wringer

      These are easily the best wading boots I've owned - solid construction, quality materials, and good design add up to make a great wading boot. They have good toe and ankle protection; good grip on slippery rocks in the river (even better with the hardbite cleats); the neoprene internals make getting them on & off easy; and they aren't too heavy. I'm a size 10, and have the 11s as per Simms recommendation, and with 2 pairs of socks (for winter warmth) plus the neoprene stocking foot they fit fine leaving a little room to move.

      What is the difference between the felt and vibram soles? Just personal preference?

      Best Answer

      My understanding is that the felt soles are made specifically for gripping slippery rocks while you're wading in a river or stream. Something like the vibram sole that is made of rubber and has lugs is typically for gripping dry ground and won't have as good of traction on slippery rocks in the water.

      One thing to keep in mind is that some areas do not allow felt soled wading shoes because of the fear of transporting mussels into river systems. The invasive species is called the zebra mussel.

      Felt is made for mossy stream beds. The felt keeps your feet very secure in that condition. However, felt is hard to sterilize and keep invasive species from being transported from one watershed to another.

      The Vibram sole on these boots is similar (although not exactly like) to climbing shoe rubber. Very sticky. It is formulated to give good stability in stream beds. It is not as good as felt on the moss beds. Simms and other brands know this. To combat the fact that it does not have as much grip they sell metal cleats to screw into the sole. Patagonia makes aluminum bars that screw in. Korkers have a separate sole that has the cleats and Simms sells the screw in cleats. They all accomplish the same thing, adding grip to mossy stream beds.

      There are down falls to felt, not just the conservation problems, but in the snow it packs into the felt and you walk on "platforms" of snow out of the river. Felt is not ideal for climbing in and out of a drift boat or for long hikes into a stream.

      Cleated treads are not perfect either for the same reasons felt is not ideal, with the exception of the snow problem. All in all, you need to see what your fishing style is. When you fish, where you fish and pick a sole that meets your needs. For the majority of fisherman the regular vibram soles will be sufficient.
