These 4 grownup boat shoe alternatives mean you can finally stop dressing like a fraternity brother

Summer's almost here, which means most men between the ages of 20 and 40 are reaching for their tried-and-true pair of boat shoes to beat the heat.

Not so fast! Men have a plethora of choices in the summer shoe department. There's a whole world of moccasin-inspired summer footwear just waiting to be explored.

With four alternatives as good as these, there's no excuse to wear those familiar, worn-out boat shoes until it's time to break out the boots again.

Penny Loafers

Oak Street Bootmakers

Oak Street Bootmakers Beefroll Penny Loafer ($328).

No longer relegated to the closets of the prep, the penny loafer has gained acceptance as a three-season casual shoe. It's a definite step up from the boat shoe - and it will get you noticed.

Driving Mocs

Cole Haan

Cole Haan Grant Driver ($168).

Many men are now donning the driving moc for activities other than driving. They have a refined, yet laid-back vibe that's ideal for summer in the city. The driving moc is often considered the penny loafer's sportier, more Euro cousin.

Camp Moc

L.L. Bean

L.L. Bean Camp Moc ($79).

A very close relative of the boat shoe, the camp moc even has the same wraparound leather lacing and general profile. However, the front lacing sets it apart, with a distinctive row of metal eyelets.

Blucher Moc

Brooks Brothers

Rancourt & Co. Ranger Moc for Brooks Brothers ($240).

The blucher moc ditches the wraparound lace in favor of full 4-eyelet system. This changes the profile of the shoe but still provides that low-profile, moc-toe summer look whose oh-so casual spirit we love.
