Women's OOFOS OOahh+ - Chalk The new shape of comfort is the OOahh PLUS. We took our best-selling slide and maximized the plush factor for a shoe that blends softness and stability. Designed to surround your foot in OOfoam™, the wide, streamlined strap securely locks you in, and the sculpted footbed hugs your sole for a cloud-like feeling. This is modern comfort with serious style points.  DETAILS: 6mm more OOfoam™ absorbs more impact than the OOahh. Wider strap delivers a more secure fit during daily movement. Designed for enhanced stability. Elevated arch and formed heel cup cradle the foot. Raised rim design protects the heel and toes.
