OOFOS · Feel the OO
You're looking at the OOFOS Unisex OOriginal Thong Sandal - Primrose.
Founded in 2011, OOFOS pioneered the recovery-footwear category — shoes engineered to absorb impact and take stress off your ankles, knees, hips and lower back after training, so you bounce back faster.
OOfoam™ absorbs impact so you recover faster.
Figures from OOFOS testing vs traditional footwear foam.
Why it works
Proprietary recovery foam that soaks up impact and gives your body a break.
Cradles and supports the arch, letting your feet and joints unwind.
Soft underfoot without the wobble — supportive enough to keep moving in.
