Smart casual is the wardrobe equivalent of a trick question. Too formal and you look like you wandered off from a boardroom. Too relaxed and you look like you gave up somewhere around brunch. Somewhere in the middle sits the right pair of sandals for men, quietly doing the heavy lifting while your linen shirt takes all the credit.
The trick is to choose sandals that feel relaxed but still look considered. Think clean silhouettes, understated details and enough structure to complement, rather than compete with, the rest of the outfit.
Here is a quick guide to getting it right, minus the guesswork.

1. Start With the Strap, Not the Story
Before you fall for a colour or a texture, look at the strap structure. This is where men’s double strap sandals earn their keep. Two straps distribute pressure differently across the foot than a single strap, which changes how the sandal sits with rolled chinos or tailored shorts. Visually, the extra strap also adds a bit of structure, so the sandal reads less “beach” and more “considered.”
2. The Neutral Palette Rule (It Actually Works)
Smart casual outfits lean on a limited colour story: navy, stone, olive, white. Sandals should either match that restraint or add exactly one contrast note, never both. A tan or black leather pair does this without trying too hard, which is the entire point of smart casual in the first place.
3. Buckle Up, Literally
Buckles read more polished than Velcro or slip-on straps. If you are choosing between finishes for men’s double strap sandals, a metal pin buckle over leather will always look more finished with tailored trousers than a plastic clasp will.
4. The Ankle Test
Stand up straight and look down. If your trouser hem sits just above the ankle, sandals for men with a slightly raised footbed and a visible strap silhouette, like the Birkenstock Arizona, tend to balance the proportions well. This isn’t about the shoe being loud. It’s about the ankle line staying clean, which is doing more for your outfit than most people realise.
5. Don’t Sleep on Clogs
Clogs for men are having a quiet moment, and smart casual is exactly where they belong. A closed-toe clog, such as the Birkenstock Boston, works particularly well once temperatures drop slightly or when the setting calls for a bit more coverage than an open sandal offers. Pair these clogs for men with cropped trousers, and you’ve solved the “is it too casual for this dinner” dilemma without overthinking it.
6. Texture Does the Talking
Suede softens a look. Smooth leather sharpens it. If your outfit already has texture (linen, waffle knit, seersucker), keep the sandal simple. A style like the Birkenstock Gizeh, with its single-strap minimalism, is a good example of letting the outfit lead while the footwear supports quietly.
7. One Strappy Wildcard, If You Dare
For warmer evenings or resort-adjacent smart casual, a crossover strap style like the Birkenstock Mayari brings a touch of movement to an otherwise straightforward outfit. It’s a small departure, not a dramatic one, which is exactly the energy smart casual is going for.
The Final VerdictÂ
Smart casual was never meant to be complicated; it just rewards a bit of attention where people usually stop paying it. The strap, the buckle, the ankle line, these small details decide whether an outfit looks put together or merely assembled. Once you know what to look for, choosing the right sandals for men stops being a debate and starts being instinct. Get that one decision right, and the rest of the outfit tends to follow its lead.
