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
  • StreamTread™ Platform
  • Synthetic construction
  • Approximate pair weight (size 10): 59.2 oz

This will typically be one size up from your normal shoe size for men and one size down for women (ie: a women's USA size 8 would take a men's boot size 7).

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.



  • 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 STREAMTREAD™ platform is designed for the angling enthusiast looking for all-round, heavy-duty wading footwear. All the styles that feature the STREAMTREAD™ platform have been proividing our faithful with years of reliable, trustworthy wading confidence.  The die-cut footbed offers a sturdy, wading-reading deck and the molded TPU heel clip offers secure heel-hold & lateral stability for all day wading security.  Die-cut and molded single density EVA midsole creates cushioning for all day wading comfort.  Die-cut, full coverage TPU retention plate allows for maximum rigidity and cleat retention for heavy duty wading.  All of this wrapped in a molded VIBRAM® IDROGRIP® rubber outsole with 3MM multi-directional lugs for slip resistance in water and toe protection.  Also available in a 12mm Felt outsole.

  • Vibram® soles are built from the bottom up and are designed to overcome very specific obstacles on a variety of terrains.

Bad soles Review by Jeff
These boots are very comfortable and I have guided in them over a year now without fail but I can't stand the vibram soles. I have even outfitted them with the aggressive cleats and slip and slide all over the place. I will be buying the same boots but with felt.

Perfect Review by Johnny
Took the boots out last weekend on the White River and they did awesome! They had great traction in and out of the water. The Boa system makes taking these boots on and of a cinch! The boot opens real wide to slip a foot in and pops open wide to slide a foot out. This boot is everything I was wanting and more!

Boa Boot Review Review by troutman
Bought these boots for a trip of a lifetime. Everything on the trip lived up to the hype but these boots. Duck taped them as the laces failed on the second day. Got back and replaced the system only to have them fail after two more trips.

Beware!! Review by Brian
These boots have very little time on the water and the BOA laces have broken 2 times. There's an obvious defect with my pair. Now i have to mail them back and be out a pair of boots during the prime time of Steelhead season! If these break while on the water, your in for a rough day. Even if you carry a replacement kit, it would be a pain to try to replace them out on the water. I wish i would have just got a pair with normal laces, it only takes a few minutes to swap out shoes laces on the river.

Excellent Boot Review by Gerry
Wore the boots four days salmon fishing and really liked them. Good traction with the cleates and easy in and out. Did hard wading and river crossing but did not get my feet banged up on the rocks. I pretighten the wires by hand before using the tension winder just to keep unnecessary pressure off the system.

Slippery Soles Review by DarthWader
Just returned from 10 day guided raft (rubber, no cleats) trip to Alaska. Boot features are fine (hence the 2 not a 1) but the boot is flat out dangerous on slippery rocks in fast water with these soles. Came very close to being carried downstream and had to be rescued. Not good on a once in a life time trip and there was a lot of water that I could not get to. Another guy had the Simms

Guideboot with same complaint and our guide will not use them. Be very careful using these boots, if conditions are as described.

Does Simms have any recommendations or can I get a refund?

Awesome Boots Review by Joseph
I have only worn them 3 times now but have stunned me. The most comfortable wading boots ever, and with not having to worry about tripping on laces i can focus on the striper on the end of my rod, easy use and no hassel i would gladly recommend them to anyone of my comrades who fish

Great! Review by Serious
Three days in and so far these boots blow my Korkers Chromes out of the water. Same great Boa System but more ankle support and better sole.

bummer Review by Parker Dave
I am a fan of Sage. I own waders, shirts, ,pants, a sweater, socks, etc. I have to say that I am really disappointed with the BOA's though. I have a pair I bought 7 months ago. I fish 5 to 7 days per month. Yesterday my wire busted as I was walking the river. After 60 days or less. c'mon man. I have to say that it was totally unexpected. It certainly made for a tough rest of the day as I gerry rigged them, which is hard with no lace holes, to work. Stick with laces people. These are great to get in and out of, however, they should not have broken this quickly.
