  1. I'm A Fan!


    I've used a combination of studs and cleats on my Streamtread Guide boots for the past 3 years. I fish around 30 days a year and, although these show signs of wear, they continue to provide good traction. There is no way I'd ever go back to felt soles as these provide superior traction. Installation was not a problem as I used an electric driver and socket.
  2. Great


    Keeps us all vertical on slimy concrete!
  3. What Problem?


    The tool provided in the kit is too short and ,therefore, hard to grasp tightly in order to force the stud into the vibram sole. BUT, no problem.All you need to do is grasp the tool handle with a vise grip and works perfectly. I had no problem inserting the studs.
  4. Limited usefulness


    Simms implies these are intended for their Streamtread boot soles. I attempted to screw these into other boot soles but they will not go in without a pilot hole. These do provide some decent traction, but definitely not on slimy rocks. They bite well on softer limestone, sandstone, and granite, but they do not bite confidently on harder quartzite. They wear rather quickly, and the screw heads become so rounded off that the wrench will not grip them well enough to remove them.
  5. I don't get it, they're great!


    I don't understand all the negative reviews. My only thought is that people are not installing these as intended on vibram soles. A mixture of star cleats and studs has worked magic for me, as far as I am concerned, and I have been on felt for almost 60 years. It was a tough decision, but I'm glad I made it. On the G3 Guide boot if you install a puck of each for the pair, you can't go wrong. I fished the Beaverkill, the East Branch, the Roach River and the Kennebec and never had a slip, even in the hardest flow and the worst conditions.
  6. Useless


    Simms should provide a refund to everyone who ever purchased these. They are 100% worn down after 2 days of fishing. They are useless and don't even protrude beyond the tread of my wading boot.

    Thank you for taking the time to review this product, John. This is not feedback we have ever heard before so if you do feel there is premature breakdown on these studs please give us a call at 1-800-217-4667 so we can work to find a solution.
  7. Lackluster performance


    I bought a new pair of G3 boots over the summer and had these installed at the shop. The screw head is too short and if there is just the slightest bit of slime on the rock, you will be slipping. I am very disappointed with Simms over this design. Generally I think Simms products are engineered well, but I think I would have been better of not retiring my 8 yr old studded guide boots.

  8. Very poor


    I bought two boxes of these very expensive screw in studs for my wife's boots. After a few outings - perhaps 8 hours in the water - most of the little hard pellets that were 'glued' to the screw heads are gone.
    Now all that I have left is some smooth screw heads.

    For the money that I paid for these, the performance and durability is shameful.

    I would not buy again and I would recommend that you look for other solutions.

    Thank you for taking the time do review this product. We recommend that you use a urethane sealant, such as Aquaseal, on the tip of the studs/cleats to ensure a lasting fit.
  9. Worn out too soon.


    I first used Hardbite studs when they first came out for felt soles. They have been in three pair of boots now & still aren't worn out.

    In September this year I got the newer set for the lug/rubber sole. They have started to ware out down to the screw head in only 2 months!
  10. Work perfect


    I installed these 9 months ago and they still work as well as they did new. Yes they have wear, but I fish five days a week. If you need more traction team these up with the Aluminum cleats.
  11. Good studs that last


    I've had these in the bottom of my Riversheds for 4 yrs and I'm in the river 50-60 days a year. I like that I can take them out for a drift boat ride (seldom have to do this as I usually bring a pad) and stick them back in to wade the slippery rocks. When they do finally start to wear down it's time to replace the boots anyway. Just picked up the 2014 G3 Guide boot and installed a new set. The compound used in the new boot should allow the studs to continue to work even when they start to wear down. Only time will tell.
  12. Duh


    Just an observation, two of these reviews open with how they installed the studs on "FELT BOTTOMS" even though they advertise them as being for the Vibrams. Silly people....
  13. work great out west


    I have had a set in my boots for 4 years they are now worn down to the point I need to replace them.... but so are the boots. I have always been able to take them out ( for the boat ) and put them back in.. I fish a bunch of rivers from rocky freestone to tail waters. Great studs,
  14. Not worth the trouble


    They are too expensive and very hard to install. The tool provided is worthless.

    Give us a call. We can make some suggestions to make the process easier. thanks
  15. good product


    I've gotten a couple years use out of one set of studs. With a couple hundred days of fishing both PA spring creeks and freestones, to salmon/steelhead fishing on lake Erie/Ontario tribs. I actually had to replace the soles before the studs. However, I am replacing the studs with the soles. I expect the same results.
  16. Caveat Emptor


    I purchased a package of these ridiculously priced studs and installed them in my felt-soled guide boots (which I love!). After exactly seven days of fishing on the Dean River they were as smooth and flat as a baby's butt. Worse yet, the remainder(s) are virtually impossible to remove, even with the Simms tool provided. When I hit the river I look like I stepped out of a Simms catalogue. I love their gear, all of it, with the exception of the ineffective and shockingly priced studs they sell. The irony is that the rocks, basalt and granite ledges studs are designed to work on are the very places that cause these studs to erode almost immediately.
  17. Worn out in one trip


    Used these on a new pair of Simms felt-bottomed Guide boots for a 6 day trip on the Deschutes. By the end of day 3 the entire head portion of the screw had worn down. For the price I had hoped they would last longer, but I can't afford to replace them after each extended trip. Hopefully I'll be able to at least remove them from the boot. Also, the set I bought did not come with a key as shown here.
