I was amazed when first putting on these OOFOS! I suffer from Plantar Facitis, and these are the only shoes that give me relief. I have another big name brand sandal especially for PF, and they do not give me the comfort and relief of my OOFOS. Im so impressed with OOFOS, that Ive bought my whole family a pair. Several friends have also bought OOFOS after trying on mine. Love these sandals!
