Korkers OmniTrax 3.0 Svelte II Soles
I work on the river so I am constantly walking on what feels like snot covered bowling balls and I will say that these seem to grip better than felt. The verdict is still out on durability and they actually seem to have a small amount of damage. Good thing is that if I'm not in slick cobble conditions I can save on unnecessary wear and easily switch them out to either of the other two sets of soles that came with my boots originally (rubber or studded rubber. Will update my review if they totally fall apart prematurely.
