If you got have felt soles, that's going to be tough to find. If all you need is a slip on boot that covers multiple sizes, and can handle moderate wading, what about just plain float tube booties a la Outcast's: http://www.flyfishusa.com/outcast/02...ube-bootie.htm? Retails same as Cabela's, but you might be able to get them wholesale from Outcast. I've heard that they are in fact just scuba boots, so you might be able to find a cheaper equivalent with a bit of searching...I'm sure there are a lot of scuba shops in you area (grin).

Another idea is, before I finally broke down and bought a pair, I was just using Walmart "water shoes" which were fine for light wading as long as there was not too much muck. Biggest downside was find a pair that would fit over XL wader booties. They do not last long, but they are cheap.

Good luck.
