I got the insulated rubber types,with the boots $59.00,which I bought from SA 3 years ago.They have worked great,but this year I have had some problems with the insulation and the rubber starting to crack.
I have been patching them since the start of the season.MAn it is no fun when you start leaking water,especially when it's cold.
I bought my sister's boy friend some Red-Head bootless waders from BPS,for 59.00 bucks(X'Mas gift).I think of picking up a pair for the next season.
But I think I will stay away from the rubber insulated from now on,and stay with the cloth-type neoprenes,with the option of what type of boots to wear.
