NWT- Never worn, still in the original packaging These were too small for me unfortunately and I didn’t send them back in time. Here is the description from their website: Pamper your feet in the OOcloog clog from OOFOS. These slip-ons have revolutionary OOfoam™ technology that absorbs 37% more impact than traditional foam to reduce stress on feet, knees, and joints. This cushioned pair is grounded with a diamond-grid footbed that promotes natural motion for all-day comfort.
