Ew I hate crocs, why do they even exist. They're ugly and provide the weirdest tanning lines ever.
I wouldn't say Sperrys are POPULAR now...I see it more as when they were popular(one/two years ago) everyone bought them and they continue to wear them because it'd be a waste of money if they didn't....plus they're not bad looking, theyre cute. But I don't see many people buy brand new sperrys now because it's more of an old trend.
Converse are forever going to be a commonly worn shoe, Uggs have awesome boots, and Vans are my favs(the slip ons).
