Hey, fellas! This spring, it's your turn to slip into something more comfortable ... your shoes. Slip-ons are all the rage this year, and we've got three cool retro ways to kick ‘em.

Preppy and Proud Of It
From broken-in khakis and tailored button-downs, to madras shorts and Lacoste's alligator polos, ‘80s prep is back. What to shoe? Boat shoes, of course. Among preps in the ‘80s, boat shoe slip-ons were the official footwear of summer. With leather uppers and moccasin construction, rawhide laces and non-slip soles, boat shoes will comfortably mold to the shape of your foot. And should you happen to own a sailboat, perhaps one named Summer Breeze, all the better.

Slip into the Sperry Top-Sider in hues like classic brown or a navy/light blue combo. Or the Sebago Docksides in solid, combo or weathered leathers.

Paying Homage to Jeff Spicoli
What do Adam Brody and Sean Penn have in common? Brody plays, and Penn once played, a Vans-wearing, hottie SoCal high schooler. Back in 1982, Penn starred as loveable party boy Jeff Spicoli in "Fast Times at Ridgemont High." His Vans of choice? Black-and-white canvas checked slip-ons. Follow
in Penn's Academy Award-winning footsteps, or choose between a variety of funky canvases like a blue and orange checker, a neon pink and blue tropical print, or a black and white
skull-and-crossbones ($25-$35).

Have your own flair for style? Design your own Vans slip-ons for only $50. Select from an online palette of patterns and colors, and in just three to five weeks, viola! Custom Vans designed for you, by you. But we just have to wonder: What would Seth Cohen do?

We All Live in a Yellow Submarine
Ben Sherman is no stranger to "The O.C"-Seth and Ryan are loyal fans of the line's fitted T-shirts and button downs. Now, the designers at Ben Sherman have created a slip-on canvas shoe that honors a 1969 Beatles classic, "Yellow Submarine." The basic design looks much like the Vans Classic Slip-on, but the pattern is unmistakably Beatles. Available at Urban Outfitters ($69)
