RiverTek Boa Boot - Light Brown


Winner of Fly Fisherman Magazine’s 2012 Best Boot category, Simms’ RiverTek® is redefining what anglers have come to expect from a high-performance wading boot. Its revolutionary Boa® Lacing System lets you lace up ultrafast—with the one-handed twist of a dial—while its unobtrusive, clean design gives you a step up in the fight against Aquatic Invasive Species. And as for the ice-encrusted laces of steelhead seasons past? Winter on the OP’s Hoh, Bogachiel, and Sol Duc systems never looked so good.

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.

Laces Review by jkeag
I rate the boot high, because I find them very comfortable to hike in. However, there are some flaws: boot topping and laces.

Within a short period of time the black dressing on the boot topping started to wear off. Now the topping is gray cloth material and beginning to wear.

In two years, I have replaced three laces. They all have started to unravel on the right foot at the middle lace point. I have run a new lace through the lace point and can't feel any scraping or catching.

The questions are: "Does Simms know something we should know?" and "Is there any solution?"

Like one reviewer recommends, "Don't leave home without extra laces, spool replacement parts, and screw tool."

Great Boot - Bad Dial Review by George
Have spent 100+ days in these boots on medium and small streams. Have hiked many miles in them to get to the small streams. However, on my last trip, the dial broke off the tongue when releasing. Don't know if it can be fixed or not. Maybe have to find a boot like this with laces.

Need better quality on wire laces Review by Speycaster
Already broke 2 in one year ! I guide in Tierra del fuego Chile and it takes a little while to have spare. Not the greatest. Need a longer last laces.

Boa lacing Review by Joe
Nice light weight boots but I cannot seem to get them tight enough in the lower section for long hikes. My feet feel like they are always moving around inside.
I love my g4s even though they are a tad heavy. Wish you did not discontinue them.
I have no trouble getting my lace ups tight enough so I will stick with them in the future.

Comfortable Boot Review by John
I have had my boots for three years, go fishing about 50 times a year.
I like these boots because of the light and comfortable snug fit it gives. Laced boots can't get as snug and comfortable as this. They are great when it is cold and lacing up your boot. The material it is made out of is really durable and takes a pretty good beating and is awesome to hike in.

The only downfall to these boots is the best thing about these boots. The laces do wear out. Mine finally broke after three years of usage. You have to plan on replacing them, plain and simple. Also the sand that gets in the dial does make it a little annoying, when I get back from a trip or a day on the river, I just spray water down the top of the dial and it rinses it out really well usually for me.

I would recommend, but you have to be prepared. I would buy another pair because of the light and comfortable boot.

Great idea, but they don't like sand Review by Jim
I have had these boots for over a year and I really liked the idea of the BOA system: comfortable, easy on and off. Unfortunately, after just a couple hours in a sandy river bottom and the BOA system locked up. Replaced the system twice and still had trouble. Laces are more reliable.

Best pair of wading boots I have ever had Review by NCBill
I have three pairs of Simms Boots, the Rivertekboa are the best of the three. The ease of getting them on and off is super great and the are comfortable to fish in all day. All of my Simms boots have the same black sole with studs. That works well for me. I was told by a Simms rep to look at the wear pattern on the soles of my shoes and place the studs accordingly on the soles of my boots and then add more if needed. Worked out greats. Happy fisherman

Outstanding Boots Review by Trout Bum
I fish between 75 to 100 days a year. I've had these boots for over two years now and have not had a single problem. I outfitted them with the tungston studs to enhance the traction as I was cautious about the rubber soles. They have good support and the special lining really helps make slides on and off very easily. Great boots.

A good boot but can be a killer Review by JoeE
These are great boots, but it all depends on the type of river your fishing.

Anything with large stones and your going to be slipping off them. Small gravel/weed rivers they work great. Ill be picking up a felt pair.

i haven't been put off using them.

REVIEW: Simms Rivertek BOA after 150+ days of use Review by Steel'ED
Purchased Date: September 2011
Review Date: April 2013
Price: $180 USD / $210 CAD (before taxes)

Length of Ownership: 18 months
Number of days used (approx): 150+ days

Frequency of Use: Avid Salmon (Chinook/Coho) and Steelheader fishing from September to May and throughout the winter months or roughly 8 months of year.

Care: Simms Rivertek boots and waders rinsed after each fishing day and properly cleaned at end of season prior to storage.

When I was looking at replacing my torn up old wading boots, I thought I would spend the money for a pair of Simms. I saw the Rivertek BOA in the store and decided to give these a try since Simms has a reputation for quality. Also, everyone who I have spoken too also recommended the Simms wading boots based on their experience with the Guide boots.

What attracted me to the Rivertek were a couple of features that I was looking for in a wading boot:
1. Lightweight and comfortable since I do a lot of hiking to get to my steelheading holes.
2. Fast draining and fast drying.
3. Ankle and lateral support for times when wading in rocky and uneven riverbeds.
4. Quick, easy, and simple BOA lacing system.
5. Vibram sole which has a reputation of quality and durability.

1. BOA lacing system: great for adjusting when fingers are cold and wet. Easy on/off even with gloves or mitts.
2. Good ankle and lateral support.
3. Drains reasonable fast.
4. Dries fairly fast as long as the boots are not left in the car overnight when it's below zero degrees.
5. Light weight and very comfortable.
6. Vibram sole gives good traction but only when the ground is dry. Studs/cleats are mandatory when wading in rivers that have have high presence of algae and rocks/boulders. Also, studs are required when fishing during the cold months when there is a presence of ice on the ground and river.
7. The flexibility to vary the stud/cleat pattern and usage with the different types available from Simms.

1. BOA lacing system: not durable and the stainless steel wire needs to be replaced at least once per year. (TIP: carry spares)
2. Trim material near the toe cap is poor quality and cracks which affects the performance of the boot (see pics).
3. Stitching of the trim near toe cap prematurely wears out and is of poor quality and workmanship which severely affects the use of the boot (see pics).





4. Vibram sole is not as durable as what I was expecting and is showing considerable wear after 150+ days of use (see pics). There are signs of separation from the upper boot and the stitching that holds the sole to the boot has been worn through (see pics).


Always carry spare BOA laces and dials with you while on the river. I had a BOA blow-out while steelheading and it was not fun having my day end early and hiking back to the car with one loose boot. I had to wait 2 weeks for my free replacement BOA laces in the middle of peak season so I decided to use zip-ties to secure the boot so I could continue to fish until my replacements arrived.

For Rivertek BOA owners, order a set of replacement laces NOW and carry them with you while fishing. Also, carry several zip-ties in a small thickness since this is what I had to use until my replacement laces arrived from BOA. ALWAYS replace the dials the same time you replace the laces. BUY your replacement laces directly from BOA since they are FREE and have a Lifetime Warranty (link below). Also, I recommend ordering a new set every time you replace the laces/dials on your BOA boots as a backup.


Would I recommend this boot to my friends? NO because most of them are avid steelheaders and they will eventually have the same quality/material issues that I have experienced. However, if you are a casual steelheader and do less than 30 days a year, this boot will serve you well and should give you several years of use and enjoyment.

For a rating and based on my usage and experience, I would have to give the Rivertek-BOA a 2 star from an avid steelheader's point of view because of the poor quality in materials and workmanship as noted above.

However, if I was a casual angler, the rating would most likely be higher because of the occasional use which would have resulted in a longer lasting wading boot and less material/workmanship quality issues.

Now in the early 2013 spring season of steelheading, I will have to use my defective Rivertek BOA boots until I can find a replacement.
