Product Care

Boa® Boot Care:

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


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. 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.

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

Never put boots in washing machine.


Boa® Closure System Care:

We recommend regular cleaning of the eyelets and reel mechanism to prevent sand and silt from prematurely wearing on the cables. Use the tool provided to remove the reel and rinse thoroughly on a regular basis. This will ensure a long life for your Boa® system.

Boa® cables will need replacing over time just like a normal lacing system.

Boa® replacement cables are available on the Simms website, directly from Boa® or you can purchase spares at most fly shops. Always a good idea especially on destination trips.

Excellent Boot! Review by Denver B
This boot is excellent.I purchased last Jul and had the opportunity to use them on my Northern cal fishing trip. I wore them for a couple days and can say they were comfortable and very easy to get in and out of. you can truly use one hand to get out or buckle up well.. Evan with socks and stockin-feet they were comfortable all day. Don't miss an opportunity to get the great pair of outdoor boots.

Fantastic All-Round Boot! Review by Yukon_fly
The main reason I picked up this boot was to test out the incorporation of the BOA system on a Simms boot. Overall I found the boot to be significantly more durable than expected with a reasonable amount of ankle support (provided you're not planning on hiking 8 miles overland to hit that unnamed creek you found on the topo map - if this is you, get the Guide Boot). The BOA system worked very well and was a significant improvement (in overall fit and tightness) over that which I've experienced with laces. My one observation though is that the BOA system requires maintenance if you get into creeks with fine sand or silt. A small trade-off for the overall improvement in fit. Lets hope we see the BOA show up on more Simms boots in the future!

BOA better than you think Review by Northern rivers
I purchased a pair in November 2011 on the way to the John Day River for winter steelhead. Wearing the boot for the first time I found, like several others have noted, the boot fit was firm to the lower leg above the ankle but lacked support on the ankle and sides of the foot. Putting the boot on for the first time all I did was put my wader foot in and turn the BOA wheel until I thought the device was taking all it could and the pressure above my ankle was as firm as I cared for. I fished for the day and found the boots to be very comfortable. The next day I spent some time putting on the boots and making sure that all the tongue material was pushed down into the boot so that the side panels of the boot could be pushed closer together over the top of the tongue. In doing this the slack created in the wire can be gathered by BOA device before it is too stressed by the force of the boot around the lower leg. Unfortunately, the little plastic wheel just does not have the torque needed to pull the wire through the guides and synch the sides of the boot nice and tight around the foot so you have to give it a little assistance. When you think about it, it's a similar act to pulling the slack out of the laces as you tighten a laced boot working your way up to the knot. If you just pulled the loose laces from the top you would not get the boot snug to your foot. Take the extra 15seconds to put on the boot properly and you will find the foot and ankle support you are looking for AND you'll still be in or out of the boots long before your buddies with laces. On freezing days double or triple that advantage.

Boa Bad Luck? Review by Paul NZ
Had these boots since September 2011. Wear most weekends for fishing various places around the North Island. I like to walk to remote areas and take good care of all my gear. I found that the boa system clogs up (with sand and grit), resulting in the dial slipping. I have guards on my waders. You can buy a tool, but my opinion is that should be free or there is something not quite right here. The stitching is coming apart mid toe area and the leather/material just below the boa lacing system is tearing. I found the grip exceptionally good, I have a mix of studs and cleats. Service so far has been disappointing. I will probably now buy the Simms G4 Guide boots, however I am a little miffed that I will be spending/spent the best part of 1000NZ$ on some boots. I am a Simms junky and appreciate their gear... Maybe this was just bad luck?

Boa Boot rocks Review by River Ninja
To the guy that wrote a bad review from Pulaski NY. Are You just *&^%@# stupid, or do you just not understand that warring these shoes on bare slippery rock coated with growth over in the NY salmon river, of course it's going to be slippery because you either need studded boots or you should just be wearing felt! I fish these waters all the way from Ohio to New York wearing these shoes in search of steelhead. I would probably kill my self, because these waters contain a lot of flat rock, with very little sediment/mud. Thats why I have studs. Nothing pisses me of more when people shoot their mouth off without fully understanding certain variable factors. But over all this is the best boot that money can buy! You just have to know how to adapt to certain situations "you need a certain amount of basic knowledge in order to begin to even understand certain concepts & how they work." AWESOME BOOT.

RiverTek Boa Boot Review by ICHItheKILLER
Love them! Very comfortable. I put HardBite, and AlumiBite studs on my pair and I had no slips while walking on smooth rock wet or dry, I also walked on rough rock and no slips. I would like the Boa lace system to tighten up a lot more stronger thats just me, I would like to know that the lace system could take the punishment, but it does seem to work very well. I will stay with the Boa model boots and buy again when these wear out.

Excellente Review by Blizfresh
This is a great boot! The boa technology makes it easy to slip on and off. I fish the bighorn in December and even when your gravel guards are frozen over. Excellent

Excellent Boot Review by Aaron A.
I have been fly fishing for 33 years and believe these are great boots for beginners and veterans alike. I recently purchased them and the G3 Convertible to replace my old one-piece wader system. I have always preferred the one-piece design over bending in waders to lace a boot but the BOA was a great answer to the boot drawback. The first use of the new system was for my recent trip to the Salmon River in Pulaski, NY. As anyone experienced in fishing the swift-moving waters of Pulaski knows, Vibram soles alone will not do the job. I actually opted for the Orvis studs because of their durability and the tendency of Simms star to pry out of the boot sole more easily. If fitted properly, these boots tighten comfortably around the foot and ankle giving stable support in any condition. Just remember to keep the BOA mechanism properly cleaned. By the way, the G3 was a fabulous performer as well.

STUDS, STUDS and MORE STUDS Review by Peter Hall
Well, I spent a week in Pulaski fishing, caught a boat-load of fish and only went swimming twice! The new STREAM TREAD technology for the textured bottom is totally useless without an army of studs (nearly twenty per boot). It's only because of the BOA system that I give these boots a rating as high as 3. It's about the only thing I've seen from Simms that didn't come close to a perfect rating. The fact that I had to add the HARDBITE STAR CLEATS and the HARDBITE STUDS, to get a decent grip was a little pricy (and really annoying to add the studs) to say the least. Keep this in mind when considering the price of these boots.

Not for the Avid Review by mbserious
I fished this boot one day on the Roaring Fork. Very easy to get on and off and the lacing system is very cool. However, if you are an avid fly guy and fish hard in difficult waters this is not the boot for you. The lacing system just cant get tight enough to support the ankles. I love Simms products, just know this boot is for more casual fishing situations.
