I have the Outfitter's for a few years now. Much use.
No problems. used the lug soles for hike in fishing & switched to felts at the water. I put the one's I'm not using in a plastic bag... they are small (narrow) & back to back take up little room. Put them in back of a vest or a pack (hike in means bring water & lunch)....
Korker's customer service is quite good!
Later,
Peter
