Crocs Baya are made of Crocs\' innovative croslite material. This material makes these easy slip-on shoes ergonomic. The footbed conforms to your foot creating a custom fit with increased arch support. For added comfort when you\'re on your feet all day, Crocs Baya have circulation nubs incorporated into the footbed to stimulate blood flow. The loose fit of these clogs allows your feet to bend and expand naturally, reducing fatigue.Croslite materialFootbed - conforms to shape of your footArch supportCirculation nubs in footbed
