I've got a pair of quicksilvers that are 5+ years old. They go below the knee and used to have a cool pattern on them. They still have the surfboard wax scraper thing whatever that's for (should be a beer opener). I use them for swimming, boating, digging and construction around the cottage. They kinda smell like a combination of ass and hockey bag when they're drying. My question is, are you supposed to get a new pair before they wear out?
