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.

Amazing Shoe Review by TK
Bought the Ripraps to use fishing out West. Shoes performed great in and out of a drift boat on the Green River, stuck like glue to the bottom of the Colorado. During the trip I lost one of my hiking boots on a hike in fishing trip in Rocky Mountain National Park. Continued hiking in my Ripraps for 3 miles up climbing 1000' in elevation, fished Fern Lake, and hiked back out 4 more miles. These shoes are AMAZING. They were comfortable hiking in as they are to fish in. Did not have any problem with gravel getting in. This was without socks or booties.

Good theory, bad reality Review by Clint
I bought these sandals because of their full foot coverage and the ability to add the "Hard Bite" cleats for “superior traction”. Well, after adding the cleats I found that the screws used to secure the cleats poked through the midsole of my sandal and into my foot! Of course, this was intolerable and even after moving the cleats to non-pressure areas of the sole I could still feel them. The cleats also come loose very quickly and really don't add traction as far as I could tell. I used these sandals in several tail-waters throughout eastern TN and freestone streams in the Smokies. I was constantly annoyed by the cleats and I was not able to remove them without much effort and/or destroying the soles so I ended up chunking the sandals in disgust and replacing them with a pair of Merrells. I'd rank the sandals alone (without the addition of the silly cleats) as adequate to slightly above average. I am surprised that Simms has such an obviously flawed product on the market.

Disappointed Review by wade4trout
Not what I had hoped for. Replaced my 4-5 year old Keen's with these. First the traction isn't that much better than normal sandals. Second sand and fine gravel still get into the shoe with no way to get it out with taking the shoe off. This is the most discouraging thing about the shoe. They are comfortable and are typical Simm's high quality. Should have just went with the sandal version.

No grip - bad sock liner Review by opete
Had high hopes for this shoe as a replacement for my felt sole wading sandals. Unfortunately those hopes were dashed the first time I stepped into the Eagle River and almost went down, following which I eventually did go down a couple more times getting a good soaking. Things didn't get better on the shore, as they didn't work on the bank side rocks either until the rubber sole was dry. Added to that, the sock liner supposed to keep gravel out didn't do that either. Then you immediately have to pull the shoe off & empty it or suffer the agony of all that gravel compressed against the foot. Good looking shoe but not functional at all. I'll go back to felt.

Best wet wading shoe Review by Justin
Best wet wading shoes I've had on. Here in Arizona, we are able to enjoy the nice cool water during the hot summer months. The Simms Rip Rap shoe provides excellent stability and comfort. The Stream Tread soles grip the ground as you jump from rock to rock and prevent gravel from entering. Excellent shoe period.

sweet wading Review by skico
I love this wading shoe. Have been using sandals forever and always have rocks under my toes. These shoes will be your favorite. I also use these on my drif boat where they really shine. Always moving around and getting in/out of the boat on mossy rocks is much better than slippery sandals.

It Has a Place Review by Nate Taylor
This shoe isn't bad and has some real benefits over previous shoe options. If you used the Keen wading sandals in the past then you will probably be pretty disappointed in these shoes but for most places this shoe will dominate. Don't use in sandy environments (think beaches or rivers with fine sand) as it will literally eat your feet. Also be careful putting in the studs as they are just long enough that you can feel the screws through the footbed and that makes them pretty uncomfortable. In terms of traction there are few things out there (including felt) that will grab like this shoe will. Very comfortable and pretty versatile shoe for 90% of environments.

My new favorites Review by Wisefish
Been searching for a wet wading shoe that keeps the gravel/sand out, has great traction, dries quickly and is durable. This is the shoe for me. After 3 months of everday use in the river, office, and on the trail I am still wearing them (even as I write this). About the only way they could be better is if they had removable insoles. I will be getting another pair if/when I wear these out. wish I could send a picture of them because they still look pretty new. aquatic/terrestrial hybrid shoe I have found in 20 years. Later, Wisefish

Rip Rap put to the test Review by Scott
Summer is the time when I love to hike up my favorite creeks fishing for hungry trout on dry flies. I feel like I have tried all of the wading shoes through the years and was excited to see the new Rip Rap shoe from Simms. As a guide and fisheries biologist, I am always looking for a wading shoe that is comfortable all day, has good grip on slippery rocks, and keeps rocks out. I used the Rip Rap hard this summer on my favorite Wyoming streams and rivers, including a three day float down the S. Fork in Idaho, and these shoes were comfortable. The new stream tread grip performed as well as stream grip does and kept the rocks at bay. On the rare occasion when a rock did find its way inside, the shoes loosened up easily with the simple sliding release lock, came off, and went back on with little to no effort. The shoes even held up to repeated four to five mile hikes up steep trails to fish remote streams in Grand Teton National Park for a study on Snake River cutthroat trout. They were comfy all the way up and back down. The cord lacing system is a bit long and once tight had to be tucked into the shoe laces to prevent it from snagging on branches wading in and out of creeks, On small to medium marble sized rocks I felt every rock through the sole of the shoe. Despite, I loved these shoes and would recommend them to anyone looking for a comfortable shoe to wet wade any creek or river. The vibram sole made the shoes comfortable on the trail and in the water. I paired them with the Simms wading sock and never had a blister or any discomfort of any kind. Way to go Simms!
