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.

Please make a high top Review by Sinking
Waded all day in these shoes along with neoprene socks and they were very comfortable. My only issue is when I ran into mud. I kept losing them and had to dig them out. Need a high top version!

These are HUGE Review by Fish101
These are absolute huge. Order 1-2 sizes lower. If you're an 11 order a 9. They are definitely made to have a neoprene booty inside, which is counter-intuitive with wet wading. Most people wet wade with no sock, or a thin sock; so these are sized WAY too big.

Otherwise, great shoe. Think Simms.. Think. Wet wading is with a thin or no-sock. Kinda common sense.

I have two pair in reserve Review by Ralph
I live in these things and burn through a pair and a half each season. I have two pair, unused in the closet in case they get discontinued or "improved"! I get blisters where the top of the heel rubs, but that is easily cured by wearing a pair of the thin Simms neoprene socks. They are flexible which at times make them more stable than cleated hard footbed wading shoes. Love them!

Excellent shoe for saltwater wading Review by Mike
I have had these shoes for 3 years and have used them extensively in Ascension Bay and Christmas Island and they have worked great! They work well with wet wading socks or bare feet equally. They are very quick to pull on if casting from the deck of the boat in bare feet and have to get out quickly to pursue a fish on a hard or abrasive/sharp bottom.

Love them Review by Paul
I've had one pair for about 15 months, and have a new unused pair.

I really like them.

One thing that could use some work is the stitching around the foot opening. On both shoes of the original pair, it's come out. I fixed it with heavier thread and a sewing awl, but it would seem a simple factory fix to upgrade that stitching.

Best summer water shoe ever Review by Dowizm
I bought the Keen version of this and always filled with rocks. These keep the rocks out. I have a 17' skiff and go from beach to beach in the Puget Sound area and am always in and out of my boat. These grip great, feel great wet and are comfortable all day.

Great for wading! Review by Vince
I used to wet wade in Keens, but I was constantly dealing with little rocks getting into the shoes. These are great because the mesh on the sides keeps all of the little rocks out. The Vibram soles grip great and they are super comfortable.

Awesome shoe that needs slight redesign Review by Lawrence
I bought these shoes for wet wading in Oregon, Montana and Wyoming. I have used these shoes extensively for nearly two years and have always used them with studs. I have only felt the stud screws in the area of my big toes and mostly when walking on pavement (pullouts in Yellowstone park are paved). When walking on soil and river beds I don't really notice it. I believe that adding a rubber insole pad would eliminate this problem. I would highly recommend to Simms that you redesign the thickness of these soles to eliminate the issue of adding studs. These shoes could very well be the best ever designed if this issue were corrected. Other than the soles they are amazingly comfortable and snug which is necessary to eliminate your feet from shifting within the shoe on rocky surfaces.

[Response from Simms Customer Care Team]
Thanks for the review Lawrence. We have passed this along to the product team. We don't recommend putting studs in the RipRap since the retention plate was not designed for them. Glad that for the most part the studs are working for you.

Pretty good wading shoes with a rub. Review by Anadromous
I bought for wet wading with a 3 mill neoprene sock which when combined makes a "good"wading shoe. I thought that maybe I could get dual use out of them while kicking around on dry ground. One big problem...the heel cup seam has no covering to protect bare skin(Achilles) from rubbing raw. I was rubbed raw in a few blocks of walking and ended up cinching the shoe so tight it was very uncomfortable but it kept the shoe from rubbing. I must wear a sock with them to keep from blistering and a sock with open port sandals is defeating the cooling effect of the shoe. At 100.00 I feel like these shoes should have had seam covers in the heel cups. It renders them amphibious only unless you want to be the dork wearing socks with sandals. Bummed a bit at the terra firma side of these shoes but very satisfied with the wading aspect. With a bit more thought this could have been a great shoe instead of good.IMO.

Shoulda bought before now! Review by BadCaster
Just spent my first day wet wading in these shoes. Performed flawlessly. Comfortable, grippy, keeps sand and pebbles out of your shoes. Way better than even the best river sandals for traction. Simms should market these to the whitewater raft, SUP and kayak crowd. Far superior traction in my experience than any of the high priced river footware you find at the whitewater outfitters. I'm going to buy a second pair to keep in reserve in case I can't get these in the future. I will be using them for fishing as well as rafting. Best thing ever!
