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.


  • CleanStream™ design elements incorporating features that include a synthetic upper that won’t absorb water, minimal exposed stitching and Boa lacing system to eliminate water & debris absorbing laces
  • Boa® M2 reel tightens laces 3-4 times faster than previous models
  • Perforated neoprene lining with closed-cell foam and full-coverage molded rubber toe cap
  • Rubber toe cap for durable protection against rocks & debris
  • TPU heel clip for added stability

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.

RiverTek Boot Review by Chad
These boots fell a part in about 100 days on the water. But Simms sent me new ones. And guess they used new thread.

Amazing Review by Andrew Malek
When I bought my G3 waders this past week I decided to buy these boots to go with it. I tryed on a few other pairs but as soon as i put these on I was sold. I have another pair of snowmobiling boots with the Boa system and I love those, After 3 year of HARD abuse the Boa system has never failed. But other than the Boa system the boots are very well built and Vibrum sole is very solid. The only downside is after walking with them on a while everything settles and you will have to retighten the boot, but really all boots are like this and you can do these with one hand!

RiverTek Boa Review by Doug
Have only worn mine once so far but was very impressed with the ease of use. By far the easiest boot to slip into and no laces to tie or come lose. Super easy to come off too. Loved it.

Great Boot Review by Jimmyrog
These are the most comfortable wading boots that I have ever worn. They are easy to hike in, have great ankle support, and just feel good on my feet. I love the BOA Closure. Forget about having to retie your boots. You can get in and out of these boots in seconds flat!The soles give me great grip. I wear a pair of Simms wading socks and I can fish all day. I just got back from a 3 day trip to the Catskills in New York and these boots did great in the Willowemoc, Beaverkill, and Delaware Rivers. It's nice to use a product made by people who use their porduct. Keep up the great work!

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.
