I've had my chippewas for maybe four to five years now . I wore out the original sole and took them to the redwing store and had them put on the same soles that I use on my redwing work boots. I believe this cost me somethin like $40.00 .. But can't really remember . Im not sure how they'd act in a swamp tho if your standing in water for a long time. I try and get across water as quick as I can and my feet always end up dry with these boots.
If your calfs are too large which I herd is a common complaint on these boots . I've herd where people have takin them to a shoe smith and they split the back then sew it up wider.
Hope this helps you in whatever boots you buy
Thanks
