The classic style of leather with unbeatable underfoot support the Chaco Leather Flip thong imitates the time-tested flip-flop design but adds a couple comfort features for an unbeatable fit. A smooth leather top sole and leather strap provide supple surfaces that conform to the unique contours of the wearer's foot. Underneath the Chaco Leather Flip thong's sculpted Biocentric™ polyurethane footbed cradles the heel and supports the arch such that it reduces pronation and encourages a healthy biomechanically correct stride. Like all sandals in Chaco's Z/rivative line the Chaco Leather Flip men's thong is equipped with a Vibram® outsole plenty durable for extended use and abuse.
