Its bit ICY out there....

Better have studs installed on your Vibram or other rubber-bottom wading boots if you plan to challenge the tribs this time of year.  In fact, it's not a bad idea to use them any time, any season, anywhere you fish or hike in to fish.
 
#4, 1/4 inch, hexagonal sheet metal screws from any hardware store will do fine and can easily and inexpensively be replaced. They are wide and have a low profile. Follow the placement pattern suggested by the boot manufacturer. Generally speaking, fewer studs are more effective rather than covering the sole with too many - unless you enjoy the thrill of dangerously sliding down large, dry rocks.
 
Tight lines and happy feet!
 
 

I have been using them for years.
They are great on rocks even the slimy ones.
Try them out asap you'll like em.
I use them year round no matter where I wade and really never slip.

Old style lace on Korkers. Best thing going. Way better than felt. New style hex head ice sandals, pretty good too. You want studs of some sort for the tribs, especially late in season when rocks, gravel may be glazed with ice.

That's crazy man.
