I picked up a pair of Simms riprap wading shoes last year for a trip to YNP where I usually wet wade.used some Simms neoprene socks and did fine on streams like the soda butte and lamar where tough wading is not the norm. On some tougher streams with algea and faster moving water I was slipping and sliding. Like Randy said, they are , unfortunately non stud compatible. Decide I was going back to studded felt for future trips and would just use my hiking boots to hike in and change into the wading shoe streamside. My Folstaf was worth its weight in gold this last trip.
Best,
Steve
