Smply the best made are the Sonic Seam by Orvis. Breathable lightweight material with a STUDDED lace boot for ice and a wool intersole like the old LL Beaners. The boot is soft and you can walk forever in them, so comfortable. The laces give you pressure around nyour ankles so mud is not a problem.Good breast pockets too! The key to warmth is not the waders but how you layer with wool and polartech. You may have to stand in line to get a pair!
