Find your perfect fit in the Women's OOriginal Sandal Navy. This guide explains sizing, width, and how OOfoam technology affects fit for recovery and everyday wear.
Quick answer
The Women's OOriginal Sandal Navy fits true to size for most feet, but its OOfoam™ recovery technology creates a soft, slightly compressive feel. If you have wide feet or prefer a roomy toe area, consider going up half a size.
How OOfoam™ affects fit
The Women's OOriginal Sandal Navy is made with OOfoam™, a proprietary material that absorbs impact and returns energy with each step. This foam is softer than standard EVA, so the footbed may feel more snug initially. The thong post is also positioned to align with the natural toe splay, which can feel different from traditional flip-flops.
Width and arch considerations
The OOriginal has a medium width that accommodates most foot shapes. If you have narrow feet, the soft foam will still hold your foot securely. For wide feet, the toe area may feel tight; sizing up half a size provides more lateral room without compromising heel fit.
Decision rules for sizing
- True-to-size foot: Order your usual US women's shoe size. The OOriginal Sandal fits most medium-width feet accurately.
- Wide feet or half sizes: If you normally wear wide or are between sizes, choose the next half size up. This gives your toes extra room without the sandal slipping off.
- Narrow feet: Stick with your regular size. The soft OOfoam™ molds slightly to your foot, providing a secure fit even for narrower feet. If the sandal feels too loose after break-in, try the adjustable version (if available) or consider a different style with a heel strap.
- First-time OOFOS buyer: Order your usual size but be prepared for a different feel. The recovery foam is softer and less rigid than typical sandals. Walk indoors for a few hours to confirm comfort. Check the return policy before ordering, as the unique foam feel may not suit everyone.
