Korkers OmniTrax v3.0 Studded Felt InsertMost guides and anglers agree that traction on the river is essential. The OmniTrax Studded Felt sole is essential in keeping you upright in adverse wading conditions. Such conditions might be winter fishing; think icy ledges, rocks or glassy ice covered slack water areas. Wait, winter what? Unknown to many, winter fishing can be highly productive and with fish podded up, the chances of multiple fish from a single hole start tilting into the anglers favor. Pair this sole with one of our Korkers offerings like the Devil's Canyon or Darkhorse or Buckskin Mary boots and you have a winning combo to tackle the most nature can put in your way.
