Below, is a press release, put out by Trout Unlimited, today.
Although, perhaps a "somewhat good idea", in obviously fighting Stream Scrunge, will it be enough? How about your wader's fabric? The crevices and creases, of your wading boots? Your boot's laces? Wading socks?

Timing is everything, it seems, even when it comes to fly fishing conservation. Yesterday, just two days before the opening of the Fly Fishing Retailer Show in Denver, Trout Unlimited issued a press release asking manufacturers to cease production of felt-sole waders and boots by 2011. While several manufacturers have already begun the shift, it'll be very interesting to see whether felt soles disappear almost completely next year, given the weight of TU's support.
