Phil,
It sounds like your Drake's & mine conspired together over the off season..... I purchased a new pair of Drake MST last October, and was quite content with the fit and warmth provided from these waders. They were inside the shed all off season, and during August/September while working on blinds I wore an older pair of canvas waders due to the heat.
Well.... opening day of the first split arrived, and so did the leaking of the "new" waders, in the same spot you described. So the hunt began for a replacement pair.
I was fairly sold on the idea of finding a pair of breathable waders for this season due to our wild temperature swings throughout our "winter" in NC. I still wanted a wader with 800+ grams of insulation in the boot, but something with reinforcement for hunting the inland stump maze swamps.
I narrowed it down to two waders, the New LL Bean breathable waders, and the Roger's "Toughman" waders. Due to the cost, (299.99 - LL Bean, 189.99 - Rogers) I opted for the rogers.
I can not be happier with the choice I made. The boots fit INCREDIBLY well, and the waders do not "swallow" you like other breathable waders I have seen. 1200 grams of insulation in the boots, and heavy canvas reinforcement on the knees, shins, and butt provide a sense of confidence against potential tears and loss of toes do to freezing conditions.
For 189.99 I really do not think you can go wrong with these waders..
Good luck with the search, it took me a while to narrow it down but was extremely satisfied with my selection.
