Electric start on mine, so it was not abuse that did them in. I did have small rips from the shifter towards the end of the season, but they leaked way before then. I was going easy on them made a air dry rack from PVC and computer fan, so it was not heat dried. I guess they don't make them to last. Sucks to hear that about motorfist, that would have been my first pick as I have their pants and they have been awesome. If I don't find a good deal on klim I may just get some columbia or keen boot, a couple of my sled buddies used them for a number of seasons without issues. Oh well worst case will ride with wet feet, I'm in warmish climate anyways. Any suggestions on a well made boot?
