The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
One nice thing about the Caddis wading shoes are they are designed to be true to size of your street shoe. So if you wear a size 12 shoe everyday a size 12 Caddis wading shoe will be the correct size for one pair of wading socks. I have three pairs of the Caddis shoes, each one a different model for different applications. For rivers with lots of rubble and big rocks I prefer a wading shoe with strong synthetic uppers that reach up above my ankles a few inches and have padding around the outside edge. In my opinion it is hard to beat the Simms Freestones.
Cut back on the squats and other free weights for a year or two.
Seriously hip boots are often more restrictive than waist of chest waders. You should consider breathable waist waders. I think the calf area will offer more room for you to feel comfortable. The cost for a decent pair is about $100. But then you also need a pair of wading shoes.
