I woudl have to second the thought on breathable and neos. I go through a set in about the same time as you and I finally broke down and decided to have a pair of both. I cannot give up the warmth of neoprene for winter fishing and they kinda suck for summer fishing and when you walk alot on those winter days. I dont spend alot of time standing waist deep ion the river, but when you do..............BRRRRRRRRRRRRR!

As for shoes, I would say go with the studs, they ROCK! I have a pair of Danners and they are awesome boots (pricey @ $120) but they have lasted far better than ANY of the others. I went to get them resoled at the outlet and they said 4 weeks so I bought another set. I almost never wear my boots that are only felt soled. You will not be disappointed. Word of caution though.....they do begin to jab you in the foot a little if you're doind a ton of walking--worth it for the traction by far!
