Product Care

Footwear Care:

For proper cleaning of your footwear 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. For maximum thoroughness, remove laces prior to cleaning. Use specialized boot cleaner, saddle soap or maybe a mild dishwashing soap with luke-warm water.

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.

Over time the use of leather conditioners may provide increased water repellency and can prevent cracking and drying of the leather.

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

Never put footwear in washing machine.



  • 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:, or

  • The New VAPORTREAD™ is designed for the adventurous angler looking for an innovative piece of footwear that is both trail-ready and wading-ready perfect for accessing remote, prisitine backcountry fishing holes.  The molded 3D footbed with arch support and ball flex aligns the foot for all day comfort and optimizes biomechanics.  A molded TPU heel clip secures the heel and adds lateral stability for all day hiking and wading.  The molded dual-density EVA midsole creates additional cushioning for hiking comfort and enhanced proprioception.  Trying to reduce weight for the trail a molded, minimal TPU retentioin plate was hidden between the midsole and outsole to provide light weight cleat retention and to enhance proprioception.  For long lasting traction on trails, slip resistance in water and toe protection, a revolutionized molded VIBRAM® IDROGRIP® rubber outsole with $MM self-sharpening multi-directional lugs was created.

  • Vibram® soles are built from the bottom up and are designed to overcome very specific obstacles on a variety of terrains. Vibram® invests heavily in research and development of products never overlooking even the most minute detail.

Vapor boot meets the challenge Review by Eileen H
I bought vapor boots after using a number of competing lightweight sticky bottom boots. Usually reluctant to purchase new products. Over the years, your competitors' boots do not last and are not comfortable for a day long walking up river corridors or fail on the all important sticky bottom technology. Fishing 100 days a year walking and wading in all terrain and river bed conditions in New Zealand. These boots are quite good- great fit, reasonably sticky and good solid traction. Perfect weight and support for these conditions. Test will be if they last more than a season. Will let you know.

Light Weight Yet Great Support, Durable, Qualty Review by Lars
I just got back from a week long fishing/hunting trip to Cold Bay, AK. Prior to my trip I was in need of a new pair of boots to go with my waders. Andy at Chicago Fly Fishing Outfitters recommended that I go with these Vapors because of the long distances we would be walking to get to our fishing locations and our hunting blinds. I thought they might be a little too light weight and not offer good support. I was wrong and I'm glad that I went with Andy's recommendation.

Durability - We were wearing our waders 12 hours in the day and as I say we typically were walking long distances through rugged terrain getting to the fishing sites and blind locations. The terrain was very rough and uneven through the tundra fields. I felt like I could have been walking in my best hiking boots and at the end of the week and they practically looked like I just took them out of the box. Clearly, these boots are well made and are going to hold up over the long haul.

Comfort - As well as these boots performed in tough conditions, I have to say that they performed every bit as well from a comfort perspective. Sometime when you want strong ankle and foot support you have to sacrifice a bit on the comfort end... not the case with these Vapors. I never once felt like I couldn't wait to get out of my boots or that I was not looking forward to putting them on.

Functionality - Well, they certainly work well when in use. They drain very well and keep crap out better than past boots that I have owned. The lacing system is standard which I like; why fix something that isn't broken. The clips for the wader cuffs are easy to hook up and better that just hooking the male clip on the cuffs into the boot laces. Little attention to details that Simms always gets right.

Summary - I couldn't be more pleased with my Vapors and they pair up well with my G3 Guide Stockingfoot waders.

boot size Review by beadhead
Bought a pair of Vapor boots. I have big (s14) feet and I travel (and fish) a great deal, so these boots should save some weight in my bags. On the surface, they look great.



My feet move around side to side in these boots even when laced as tightly as possible. The only solution for me is to fit two insoles into each boot. Hardly a ringing endorsement for Simms!

If they fitted, they'd be the perfect 5 star boot. Too bad.

Great lightweight boot Review by Jon
I purchased the Vapor boot in hopes of finding a lighter weight wading boot I could hike in. I walk a lot when Im fishing and conventional wading boots can be a pain to hike miles in. Simms absolutely nailed it with the Vapor boot. Ive spent half of the winter and all spring in it and so far Im very impressed. The price point is great as well, and Id recommend this boot to anybody that wants a lighter, more hiking friendly option. Nice work Simms.

Great lightweight boot Review by Wichita
Great lightweight boot with solid ankle support. Feels like wearing tennis shoes instead of heavy luggish boots. Might buy a second pair.

great all around boot Review by altazor07
After a very thorough vetting process, I recently decided to purchase a pair of the Simms Vapor boots. They are easily the best pair of boots I have ever worn on the river; the support of the boot coupled with the ability to walk and wade securely is a revelation. In short, some of my other wading boots had plenty of ankle support and some of them had the dexterity you might expect from a lightweight boot. Until the Vapor, I did not think a boot existed with both attributes.

This past weekend i put in over ten miles on the new boots, over rocks covered in slime, as well as on and off trail. I have to say that my feet never got tired, and i started imagining ways i could make the EEE wide boots fit my feet, sans waders, for everyday use. Alas, i am not wearing the Vapor boots to work, but they are stylish enough and comfortable enough that such a thought is actually feasible.

This is a great pair of boots.

Lightweight Review by Wichita -- Durango, CO
Great boots with the G3 waders -- extremely lightweight in the river. Be sure to order one size greater than your normal foot size.

A comfortable walker and great stability in the river Review by Daubie
Simms Vapor Boot Report:

My only pair of boots prior to these were an inexpensive pair with felt soles. While walking I could never say it was painful, but it was never pleasant either as the boots had little give and reminded me of wearing snow ski boots. Traction was always good in the river but it seemed as though the felt masked any transference of "feel" to my feet, leading to constant stumbling as though I had no balance.

The Simms Vapor are lace up and typical with Simms boots you need one shoe size larger than your street shoes. The first set of lace hooks are set far to each side of the boot and will take practice to catch easily but there was plenty lace to double knot the bow tie. Walking in the Vapors was a joy, very light with a good bend at the balls of your feet (no more ski boot effect). They fit my heel very well also, eliminating heel slip and giving great ankle support. I don't know why but I completely forgot to buy cleats, but once in the water found they wern't needed. The traction was good, almost as good as the felt (walking on fist and double fist sized cobble stones with light moss coverage) but because I had better transference of sensation to my feet the stumbling I normally suffer was completely gone. The boots also appear to conform to the rocks giving you more surface contact. I would never say that these boots don't need cleats but for my home waters, sensation transfer and more conformance to rock structure I don't need cleats on my river. Only time will tell their durability.

I rate these boots very high and feel safer when in the water.

Love my new Vapor Boots!!! Review by Tom
These wading boots are simple, lightweight, and not to mention have a pretty cool look and style. I saw these boots at the 2014 Fly Fishing Show in New Jersey at the end of January, and at first I was a bit skeptical due to how thin the neoprene lining was compared to my other brand wading boots that I was replacing. I thought that my feet would be cold in no time, especially fishing in the cold waters of New Jersey in the winter months. I tested them out at the Pequest River in the beginning of February on a 32 degree mid-day and along with Simms' ExStream Wading sock and Liner Sock along with the neoprene stocking foot of my new Simms G3 Guide Waders, the Vapor Boots kept my feet satisfyingly warm, sweat free, and didn't feel like I was wearing "Frankenstein" boots. They were light on my feet and I was making new trails trough the woods, in several inches of icy snow, to find fishing spots for much of the afternoon. I felt like I was wearing light weight hiking sneakers! On top of that, they dry so quick compared to my other clunkier wading boots. Simms definitely knows what they're doing and I believe I can have trust and faith in the products they put out. Thanks Simms!

Basically a lighter weight version of the Rivershed with a lean towards hiking Review by John H.
I do a lot of back country angling and put a lot of stream and trail miles on my boots. I had been using the Rivershed boots and found them to be the best boot for the task. When it was time for a new pair, I decided to try out the Vaportreads. They basically performed the same in the water, and on the trail they performed more like a hiking boot allowing me to travel faster and with more traction. As for the prioperception, I couldn't tell any difference. They were able to shave off a few ounces of weight, but there is still no connection between your feet and the bottom of the stream like they claim - felt is still the only way to go from that perspective. However, hiking long distances (oftentimes with the weight of a pack) requires a stiffer sole so your feet don't get tired, so I wasn't as worried about the lack of any prioperception as much. I got these boots to give me traction in the stream and on the trail, and that is what they do (I only recommend using them with studs when it comes to the grip on the stream/rocks). I also can't understate their success as a hybrid hiker. I literally took them out of the box and took them on a 10-mile round trip hike-in fishing trip. I had no blisters, sore spots, or any other issue with my feet. That is good for a boot that is well worn and broken in, and just unheard of for one right out of the box.
At the end of the day, I couldn't tell much difference between them and the Riversheds in the stream, they were better on the trail, and they are $10 less than the Riversheds, so I am happy with them. It will take time to truly know, but I hope they also mimic the Riversheds for durability, as I am rough on boots. Most boots last me one year, and the Riversheds lasted me two. My expectations of the Vaportreads are two years, as well.
