Once upon a time, I was very excited about Korkers because of the ease of swapping soles. In the end neither of my pairs lasted long enough to be resoled and broken Boas led to some long and awkward walks out of the bush. I've moved on to the Patagonia River Tractors, which have incredible all around traction but are quite heavy, which gets old because most of my fishing is long walk and wades.
My wife reports that her Vibram Simms boots that I maxed out the Alumabite cleats on have, like the River Tractors, much better traction than felt. That soft aluminium is magic. I really want to get my hands on the new Simms Ultralights with Alumabite cleats. Have any Calgarians noticed them in stores? I was hoping to pick up a pair when I'm up there at the end of the month.
