For an on-the-go, active lifestyle, athletic sandals are a safe alternative to flip-flops. Unlike athletic sneakers, feet are exposed to the open air, making these shoes a popular choice during warmer months of the year. Many designs feature buckles and straps that prevent them from slipping off your feet, making these shoes safe to wear when hiking and riding bicycles. Athletic shoe giants like Nike and Adidas sell sport-ready sandals with adjustable Velcro straps and cushioned toe gels that provide added support and comfort. Teva, another popular athletic shoe manufacturer, sells durable -- sometimes waterproof -- sandals suitable for outdoor activities like white-water rafting and fishing.
