Color

Sounds simple enough, but even the subtlest combination of two-tone sandals can completely change your look. Earth tones like browns, dark greens, or tans are great to wear for nature excursions, camping outings, or walks on the beach. Black or blue, or a combination of the two will look great when you are out at social gatherings; these shoes can be dressed up with a polo or button-down shirt.

Straps

Thong flip-flops are just about the most basic type of sandal you can have.  They're best when you are trying to keep your look minimal or you just need something to get you from your car to the water. Sandals with one big strap across the top of the foot are a better choice if you need a slightly dressier aesthetic. One thing to keep in mind: the more straps there are on a sandal , the sportier the look.

Design

Flip-flops  and slip-on sandals are totally casual, but the latter can be worn for dressy-casual events. Sporty, rugged sandals with multiple straps are useful if you expect to get them a bit roughed up and dusty during outdoor activities.

Fit

Again, this sounds like an obvious consideration, but the more wear you will getting out of a pair of sandals throughout the day, the tighter grip you will probably want them to have around your feet. If you are going for long walks or on hikes, choose a shoe with at least two or three straps that wrap around the top of your foot and the back of your heel. These will help your feet stay secure, so your feet will be comfortable for longer.

Lounging Sandals

Also known as a recreational sandal, these shoes can be worn for all informal occasions: lounging by the pool, hanging out at a barbecue, and so on. Crocs ABF Pro Sandals  quickly slide right on or off, and they are made of lightweight materials--a nice feature for sandals you'll only use around your house.

Vacation Sandals

Men who are worried are their street cred probably won't sport sandals  in the city, but when it is time to head to the beach, they are definitely more appropriate than a pair of Nike Dunks . Look for sandals that feature both style and comfort in case you venture off for a hike or a long walk along the shore.

Formal Sandals

I know what you're thinking: how many formal occasions are there that call for flip-flops? Well, in case you should find yourself in a tropical location for a wedding or birthday, be prepared with a nice pair of Kenneth Cole sandals  or Timberland Earthkeepers . They are rugged yet have a sleek, simple look and are great to pair with a button-down and shorts or slacks.

Urban Sandals

A few years ago, there was a huge uproar within the hip-hop community about men and sandals. Rapper Cam'ron  took shots at superstar rapper Jay-Z  when pictures surfaced online of Jay-Z wearing sandals while on vacation in the islands with then-girlfriend, singer and actress Beyonce . Cam'ron stated that no man in hip-hop should wear sandals, while Jay-Z stated that he was on a tropical island  where the weather was over 100º and sandals were necessary. Is it possible to wear sandals in the hip-hop community without facing taunting? Yes, if you choose ones that reflect your own personal style and comfort.
