Feel the OO - An evolution of the OOriginal, the OOahh Slide features an agile foam strap for additional support and comfort. Like every OOFOS shoe, it features OOfoam technology & the patented footbed. Made for Recovery - When you’re always on the go, the demand on your joints can translate into fatigue, muscle tightness & pain. At OOFOS, we don’t want to slow you down. Our shoes are designed to help your body work less—so you can do more. I bought these shoes while dealing with some plantar fasciitis, they were recommended by my primary physician. I really wanted to like them but they did just not fit me. I wore them around the house for a few days and they ended up in the closet.
