The OOahh is a slipon, aftersport slide made of OOFOS' breakthrough OOfoam. It holds tight and conforms to your foot, ensuring incredible impact absorption, arch support, and natural motion. Ideal for post-workout recovery, it's also moisture and bacteria resistant, making it great for the shower. OOfoam absorbs 37% more shock than other materials, reduces stress on feet, knees, and lower back, and cradles your arches. The biomechanically designed footbed allows natural motion, and the soft, conforming toe post eliminates chafing. It's shower and beach-ready, moisture and bacteria resistant, and doesn't retain smell. The durable OOfoam holds its cushion and is machine washable.
