Warm weather + footwear = sandals. For a trip to the beach, a cruise vacation, or a resort retreat, a great pair of flip-flops or sandals are a must. They are comfortable, stylish, and help to keep your feet cool. Sandals are so versatile; many styles can pair with a casual outfit as well as a dressier look. They’re suitcase friendly too, being small and lightweight; be sure to bring a few pairs.
