Central Montana is home to cowboys, roughnecks, and fly fishers, all with three defining traits—spurs, steel toes, and Simms. For those occupying the latter category, Simms’ G3 Guides™ raise the bar with a RiverTread™ platform bolstered by proprioception, which minimizes rigid underfoot materials in order to enhance feel whether on the trail or in the water. Additional features include TPU molded heel clips that lock in fit, while the neoprene lining stacks cushioning where it counts, keeping feet warm and delivering easy on/off performance.

Simms G3 Guide™ Boot

Product Care

Guide Boot Care:

For proper cleaning of your footwear to descrease the likelihood of spreading Aquatic Invasive Species, please reference our CleanStream™ page.


Guide boots are made water-repellent full grain Nubuck leather.  They require little maintenance but should be cleaned and dried.

If using in saltwater always clean and rinse to prevent corrosion.

Use a brush to remove dust and dirt. Choose an old vegetable brush or toothbrush. For maximum thoroughness, remove laces prior to cleaning. Use specialized boot cleaner, saddle soap or maybe a mild dishwashing soap with luke-warm water.

Do not use bar soap or detergents.

Do not place wet boots close to a heat source (fireplace, campfire, wood stove, radiator, heater, sunny windowsill) as this can weaken adhesives and cause materials to become brittle or shrink.

Dry using natural methods (air dry) and try to keep them out of the sun for long periods of time. Boots dry faster when positioned upside-down. If desired, stuff a sheet or two of newspaper into each boot to absorb moisture. Change the paper each hour.

If you see any mold on your boots, brush in a mixture of 80% water and 20% vinegar.

Over time the use of leather conditioners may provide increased water repellency and can prevent cracking and drying of the leather.

Store boots in a place where temperatures are stable and normal. Do not store boots in attics, garages, car trunks or any unventilated spaces.

Never put boot in washing machine.



  • CleanStream™ is a design philosophy that runs through our line of wading footwear. While not specific to a product feature, this designation does indicate that the product includes features and/or materials that are more resistant to "hitch-hiking" organisms – have less exposed stitching, fewer ridges & pockets and utilize non-absorbent materials – all making the boots easier to inspect, clean and dry faster. All of these elements assist anglers in doing their part to prevent the spread of invasive species. For more information, please visit our CleanStream™ page or these organizations: www.cleanangling.org, www.protectyourwaters.net or www.tu.org.

  • The New RIVERTREAD™ platform is designed for the demanding angler looking for the best wading footwear on the market.  RIVERTREAD™ features Simms’ latest engineered components to maximize comfort, performance, and slip-resistance.  The molded 3D footbed with arch support and ball flex aligns the foot for all day comfort and optimizes biomechanics.  Molded dual-density EVA midsole creates extra cushioning for hiking comfort and enhances proprioception.  A Molded and minimal TPU rentention plate allows lightweight cleat retention and enhances proprioception.  A molded Vibram® Idrogrip® outsole with 4mm self-sharpening multi-directional lugs permits long lasting traction on trails, slip resistance in water and toe protection.  Also available in a 12mm Felt outsole.

Great boots nut need tweeking Review by BigHiz
Purchased a pair of the G3 guide boots felt and ties them, the way the came. and with every type of stud simms sells and others sell. They are all ok but nothing like the old studded felt made years ago. What I did was cut the stitching and yanked the felt sole off the boots and got a replacement studded felt and had a shoemaker re stich them on the boot and now I have the greatest wading boot money can buy. What you gotta do for a great pair of wading boots.

Boots built for the pro Review by Roscoe
I am a professional photographer spending a lot of time shooting fly fishing and spend at least 150 days on the water. These boots go the miles. They fit great, long days on my feet shooting fishing and my feet feel great. ive put over a years use on these and the only thing that has worn out is the laces. they are rugged and built to last.

Excellent! Review by PA Dave
I am not a hard-core fisherman - I also hunt, bike, hike, etc. so I simply have limited time to be on the stream. These boots are excellent - built to last, comfortable and well-designed. I am a size 11.5 street shoe and the size 12 fits me well. I will probably buy the rubber soled-model next time because I suspect they will be a bit lighter while being used.

New G3 Wading Booths Review by stelhd
I've owned either Simms G3 or G4 wading booths for years and can truthfully say that I think this vintage of G3 Guide Booths are the most comfortable. I have a pair of five year old G4's that are like new because they are like wearing a pair of concrete blocks, so they collect dust in my garage. But, not these new G3;s, they go an and off easier then any of the older styles and are comfortable to walk and wade in. I like the new style of soles and will be interested to see how they last in the rocky rivers that I fish in.

Great Fit and Feel Review by Wes
Just got these boots to replace a different brand that I was having real trouble with getting my foot in. It took me forever to get my boots on! Then I got these and wow! The tongue really opens up so you can just slide your foot right in. And they have great room on the inside while wearing two socks plus the neoprene from the waders so your foot doesn't feel to crammed in there. Great stability and nicely built! Glade I made the switch to Simms boots!!!
