I got a pair with felt soles (& rubber lugs) about 3 years ago. I like the fit, felt like nice hiking/walking boots.
After a car wreck, & nearly a year of recovery, I got to use them. There's a particularly steep incline down to the Middle DesChutes river... I walk down with the rubber lugs, fish with the felt & walk back up with the rubber lugs. That's a GREAT option.
However, I did eventually find them tight. I could only wear the boots with a liner sock & waders (or neo booties). NEVER had a problem with soles coming loose. Also found their customer service MOST helpful... I wanted a third sole (they recommended one) & had another minor issue, they dealt with it immediately.
IF they fit, I'd recommend them whole heartedly.
Later,
