i would second bruno's suggestion , i have the chota stls ,and they wear like iron in my opinion , i replaced the pair i have now in june and i have over 60 days use , meaning 8hr fishing trips as a average out , and no signs of wear other than on the one boots speed laces . how much u wear a wading boot says alot about the quality thats why i feel everyone who recomends a boot ,tell everyone how much u use them. I am not retired by a long shot ,but i am in the second phase of getting help for my fly fishing problem.
