The Xtra-Bite Carbide Screw-In Cleats give a Korkers Chrome Lite or Stealth Sneaker wading boot the bite it needs on algae-covered and mossy river rock. Tungsten-carbide construction holds an edge through repeated contact with slick stone, and an auger thread design locks each cleat in place so it doesn't work loose mid-wade. These cleats are built for the Chrome Lite and Stealth Sneaker soles specifically and will damage an Omnitrax or other Korkers sole if installed on the wrong boot. What Our Gearhead(R) Experts Are Saying:"I've crossed slick, mossy ledges in these without a single slip, and the bite holds up wade after wade instead of dulling by midseason."
