I'm up to 3 seasons on my DC Scouts and I beleive this will be the last one for them. What started out as a great fit and ultra comfy ride has turned into a sloppy fit and not so comfy ride. Plus the exterior of them is getting pretty beat and I'm a little worried about some really thin spots on the fabric. I think it becomes fairly clear when you need to replace your boots.
EDIT: WOHOO FOR 1,000 POSTS!
My internet street cred just went up a little. LoL!
