Kling-On Deck Sole is non-marking sticky rubber that grips on dry and wet surfaces. Perfect for fishing the flats. Traction: The unique micro-lug design maximizes surface contact in all directions, while razor cut slits disperse moisture boosting grip on smooth wet surfaces. Fit: Match the sole size with your OmniTrax® 3.0 boot for a perfect fit. Please Note: Korkers Omnitrax v3.0 soles are compatible ONLY with Korkers boots that use the Omnitrax sole system, and do NOT attach to boots from other brands.
