Getting ready for the shore cod season, I bought some mail order size 10 Ocean Waders. On arrival and having tried them on, the calf area is extremly tight, compared to the rest of the fitting, is this normal or are they all like this?. I had a pair of Oceans about ten years ago heavy duty rubber, but I cant seem to find any around, anybody know where I could get some, unless my calfs shrink the new ocean waders are no good. I have also bought some ron thompson crosswater neoprene and they seem ok. advice welcomed.
