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.

The tightening mechanism is made from plastic which is connected to the boa system with a weak plastic stem and a tiny screw. BREAKS very easily. Mine broke second time out !!! Then sent them back over a month and a half ago and still haven't got them back !!!!! I see they now sell a field repair kit for an EXTRA 12 bucks, they must know they have a problem with the design !!!!!!! Would not reccomend !! Going back to my tried and true Korkers.

Finally... Review by Ariel
These boots are so comfortable I thought I had purchased the wrong size! Lighter than any of my other Simms boots, the Boa was not only easy to get on, comfortable walking on dry land, rocks and grass, but the fit was exceptional. Priced right, I have no problem recommending this boot to my clients. My only suggesting would be to make the knob of the thightening mechanism square instead of round. This would allow the user more leverage when tightening in all weather or when hands are wet.

Simms Good BOA Bad Review by Tim
I bought these boots based on the life time warranty on the lacing system. So I was quite disappointed that within a year of purchase the cables on both boots failed. I have ordered a set of new cables from BOA at no cost and am waiting for them to be delivered. (10 days and counting) In the mean time I purchased two repair kits at $15 a piece from two local fly shops. I purchased the first one and when they mailed it to me it only had enough cable for one lace so I had to get another. I replaced the cables in the boots. I also required a pair of needle nose pliers and a good set of wire cutters to get the old laces out so I suggest that anyone that has these boots, that they should inspect them before leaving the house, field repairs will be frustrating at best. I would not suggest these boots to anyone who spends any amount of time on the water or who tends to walk any distance. Unlike laces which can be repaired with a simple knot, if the BOA system fails your boot becomes next to useless. These boots and the lacing system is a gimmick not an innovation. The lacing system may work in a clean environment like snow or pavement but in sports where mud, and grit is present they just won't stand up. I have had very good service out of all my Simms products to this point, and will continue to buy Simms products but I would suggest that Simms pulls this product out of their line immediately. With such a great reputation for excellence these boots don't make the cut.

Are you sure these are Simms boots? Review by Corey D.
I have owned many Simms products in the past, and the one thing that I like and have come to expect most about Simms products is the quality. Regretfully, I am very disappointed in the quality of this boot. I have owned these boots less than a year, and the stitching is coming apart around the toe cap area. The rubber toe cap material is splitting, and the laces started fraying several months ago. Both laces broke yesterday while on a fishing retreat with some friends on the Current River in Missouri. I had to wrap the boots in duct tape to keep them on my feet. I will be shopping for some new boots in the near future, and I will probably be looking into boots from several competitors depending on how Simms will take care of me on either repairing or replacing these.

best boots ive ever worn! Review by c. heim
I bought these boots on the recommendation from Tim at angler's covey here in colorado springs. I used the korker's system prior to these boots and the RiverTek's blow those korkers out of the water. I have a messed up knee and for me sure footing is paramount. I have used these now on the south platte, the arkansas, and several small streams in colorado and these boots are the best things ive ever worn in a river. i also have the carbide cleats on them which makes my feet feel cemented to the river bottom, no slips or slides, even with a trick knee. They drain quickly, easy to get on and off and like i said, the grip is amazing. if you're even considering these boots, do yourself a favor and just buy them, you won't be sorry.

Awesome Review by Laxdrewb
These are awesome boots. The material is light weight and durable. Great for a descent length hike to your spot of choice. The new Boa system works well. What I enjoyed most was that in a cold 5 degrees they were fast to put on and didn't freeze up, which made them easy to take off.

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?
