Get your mind out of the gutters! Shoelover is talking about the morning after a transit strike that probably left thousands of people with............blisters.............from walking further than their couch.
Anyways, time to put away the couch potato hate and give out some blister advice.
Try some Bodyglide on your feet. Originally marketed towards athletes to prevent skin chaffing, it can also be used to reduce the chance you get a blister. Additionally, if you are reluctant to give up your couch surfing ways in the future, you can use some of this between your skin folds in the summer (OK, Shoelover's last shot at couch creatures).
