The only issue mentioned so far is the rubber heel, that can be remedied by a $4 heel tap which also prolongs the overall life of the heel. It's still a pretty amazing deal considering the price of these side zips compared to the main lines imo.
I have not. But I have wiped them down once or twice. Again, I highly suggest adding heel taps to the side zips. They will prevent the heel issue some are saying they are having, and will also prolong the life of the heel.Here's mine with about two weeks of wear. Got taps on the first day. [[SPOILER]]
