The Boda BUGrip is a waterproof winter boot with carbide-tipped steel studs embedded permanently into the outsole rather than strapped on as a separate traction device. That means the grip is there on glare ice without the clumsy over-boot feel of crampons, and it doesn’t come loose or wear smooth the way add-on ice cleats do. Icebug builds the upper for daily wear, so it’s as comfortable on cleared sidewalk as it is on a frozen driveway.
