If you keep putting baking soda in your boots everytime you use them, the soda will eventually eat through the soles. Sweat and soda together make a deadly combination on boots and shoes. Have you ever tried Muck boots. They may smell after you sweat, but after a day or two, the smell is gone. I have two pair and I love them. They are 100% waterproof. I use the fieldmaster in early season and turkey season,and the woody max when it gets cooler. They are lightweight and very comfortable. They are neoprene uppers and rubber lowers. Check them out if you already haven't.
