Let’s make it clear - there are few careers, offices and dress codes granting sandals in business environment. Sadly formal style requires attire that rarely is comfortable but it should enhance and transmit your professionalism and show respect in the first place.
That is why you ought to shun wearing sandals to the office. 9-5 workers should put on moccasins or openwork Oxfords.
Men find an ally in summer as during that time of year they can slack off and dress more comfortably. Timeless linen, returning each season like a boomerang, is a blameless backdrop for leather sandals. If you decide to expose feet do it with style. Opt for brown, black or sand leather sandals to go with loose-fitting pants or knee-length shorts. Be wary of faux leathers and velcro-fastened models.
It’s good to finish off weekend outfits, especially those that carry some function and provide comfort during physical activity with sporty sandals. Rubber or foam flip-flops are a go-to for the beach, while velcro sandals equipped with massive soles are destined for the off-the-grid excursions.
If you are not a fashion week denizen and your fashion whims can be portrayed by occasional flashy tie, forget about wearing socks with sandals. Be informed that fashion avant-garde allows that combination. Such coups can be seen on runways all over the world. To answer that question, fall back on you fashion sense.
