Tungsten studs - Put these studs in a new pair of Drift boots about three months ago. They work well, haven't lost one yet, they still seem very secure and haven't worn down much at all. I'm out 2-3 days a week so they've had a decent amount of use. I put them between the tread as suggested but they seem to still have enough bite to make a big difference.

The answer - I have put these on a pair of Simms Tribuataries that I bought specifically for putting studs on. The Tribs have a stitched sole on a solid last. I used 11 studs per boot - so needed two packs of these studs. They are absolutely brilliant. If your boots have modern molded soles, any studs probably won't stay in. The screw heads need to reach the last of the boot.

Boot studs - Good product at half the price of the last studs I purchased. Great service

tungsten studs - have put these bon a set of waders they work really well no more slipping and sliding on the rocks in the Tongariro river

Great while they lasted - Worked really well but lost a couple of studs each day on the river. Thread needs to be longer. Too expensive for what they are

Disappointing - Delivery was excellent, only a couple of days. Studs look the business but required a special tool to install which was a pain. First day in Tongariro they worked really well. Next time experienced slipping & found half the studs had fallen out! Very disappointing.
