The first fully closed shoe to feature OOfoam technology! We combined the OOFOS patented footbed design you know and love with a 4-way stretch mesh upper to create an unbelievably comfortable shoe that enhances the recovery process. Take the stress off your tired soles, joints and give your feet the freedom of natural movement in a shoe you can wear all day, every day. Great pre-owned condition with some minor signs of wear as shown.
