I didn't run a search on here for this so it may have been covered already. Went out tonight to find my wife a pair of non-felt sole boots this weekend for dipnetting. Tough to find any in her size. But, I was amazed at how many places were still selling felt soles. Fred's and Sports Authority to name a couple. At one of the Sports Authority stores, the manager was upset because they sent him a whole pallet of felt soles. He sent them back, but was told the other store had some in. We went to the other store, they were all felt sole. And the employees there just said "well, that's what the company sends us because they don't read the regs in all 50 states."
My guess is a lot of people are going to get busted for felt soles this year (1) because they didn't read regs, but also (2) because they went and bought themselves a brand new pair of boots that were illegal to use. Wish Fish and Game had some authority to get that stuff off the shelves.
