Just got this email from Blue Ribbon Flies:
"Korkers Grey If you're looking for a lightweight wading boot with the versatility of rubber, felt or studded soles, Korkers will cover all the bases.
Over fifty years ago the first Korkers product was created in the basement of Korkers' founder. Made by hand using scrap rubber, nylon cord, and carbide spikes, Korkers "River Cleats" were born. The functional, yet versatile design of the cleat system quickly grew as a favorite among fishermen, and spread to provide traction safety to a number of industrial applications.
Today, under new ownership, Korkers has taken the fundamental values of Korkers original design of functional and versatile footwear to another level. By incorporating OmniTrax V2 Interchangeable Sole Technology, Korkers has developed a full line of versatile footwear systems that gives you the unique ability to maximize performance, despite conditions. No matter where your next adventure takes you or what surprise mother nature might throw at you, with Korkers you'll always be ready.
Blue Ribbon has just started carrying Korkers, and we already have a discontinued color (grey) in the Torrent Trail Shoe, and have marked it down to $54.99 in men's sizes 9 - 13. The brown version is $99.99, and the interchangeable soles are $24.99 per pair.
If you want the choice of felt some days and rubber other days, or if you want to trade out the studs for the skid-proof boat-safe soles, Korkers will give you all the options."
I would jump on these. These are the best wet-wading shoes I have found. They're great for hiking too. And at that price....
