obenaufs or sno-seal, but they probably won't look like that ^ afterward! on a side note, I sent my boat shoes back to Quoddy to get them resoled, and just got the notice that they are shipping them back to me. $25, shipping back to me included, and it took no time at all. they were also very friendly. i chose to call them rather than email, and it went really smooth. Yeah I think they will darken the laether drastically. Want to preserve the color as much as possible.
