I purchased the "Chrome" Korkers about 2 months ago. I went ahead and got the sticky rubber and studded sticky rubber soles. They are the best wading boots I've ever used. I've had numerous boots over the past 40 years and the Chrome Korkers are the most comfortable ever. The stainless steel lacing system is awesome. Quick and easy to use! This is the first pair of non-felt soles I've ever owned and they are a breeze to clean after each outing. The newest model (2011) tightens much quicker than previous models. They are a bit pricey, but I give them 5 stars. BTW, Kokers has resized their boots to fit larger than your actual shoe size. If you wear a size 11 boot or shoe, order size 11 Chrome Korker boots. They will be plenty big enough. But if your shoe size is for example an 11-1/2, order a size 12. Also, the sticky rubber studded soles grip as well if not better than any studded felt sole I've ever used. This newer generation sole from Korker is wider than previous soles. That equates to more gripping surface. I've used them about a 8 to 10 times so far, and they work superbly! Hope this helps.
