Actually, the hexs seem to be wearing the most after 2 yrs and are almost now all rounded, but still grip great. You are right, the "Red" more permanent option for fixing the hex nuts to the soles would work better and avoid loss of lugs during a trip--but originally, I wanted the option of being able to unscrew some if I didn't like them as is.
I have had them 2 yrs now fishing several days a month and they are holding up great!. I just recently replaced the felt soles with new ones since I wore out the old ones. This is a great advantage since on my old Simms it was a fortune to replace them. I just ordered a new sole and popped them on. ALso, on a recent PHWFF outing, I replaced the soles with the aluminum disks for extra traction while climbing up muddy banks and holding up the veterans at the same time. Worked great - still super comfortable.
