I have a pair of the Orvis Pro Guide boots and I have to agree with @Nick Clayton about their comfort. Especially the soles. I never walked in anything so cushiony. I do have an issue with the upper part of the boot just above the ankles. After wearing for a while, they make me a little sore. But it is only when out of the water and walking. They are the cat's meow when wearing in the water. I actually had an email exchange with the lead designer of these boots and the Pro Approach Wading Shoes and he told the boots do need to be broken in a little.
