Amazing what a difference a decent suit makes, hiking gear isn't any good as you are kept warm by hiking itself to a larger extent, shore fishing standing still is a killer (not as bad as sitting static chub fishing at night mid winter at -7 but,, )
Get yourself a flotation suit, something like a Sundridge 2 piece and some warm boots half the battle is done, the sundridge suits also have hand warmer pockets I can't begin to tell you how much I love those things lol
