I tested out the Sonic Pro's and the Redside boots out at Bennett Spring. The Sonic Pro's were bought on a pre-Christmas closeout sale from The Caddis Fly Shop, $170, a really good deal. I bought the boots at bass pro. The waders, with their sonic-welded seams, felt more like baggy wants than waders, a comfortable feeling. They haven't leaked they feel like they are built solidly and very durable. The seat is 5 layers of material compared to 3 on most of the wader, a good addition to people who sit on the bank or sitting in general. Overall, the waders are great and I would recommend them. The Korkers Redside boots, with their interchangeable soles were great too. The Redside boots have a quick lace system, not a BOA but it is good for getting in and out without having to bother with more knot tying. The soles that I wore were the sticky rubber soles. The sole interchange system is good if you need to switch soles from river to river, but I don't really go to a lot of different rivers so I bought them to go between studded and unstudded rubber. I tried out the quick change system before I went to the river and snapped one of the soles by the heel, it was my fault because I didn't really know how to take them off so I tried to pull straight down. I did not break the other sole after I watched a video on how to do it. The soles are about $30 a pair. Both of these products make a great combination and I hope they will last a couple of seasons.
