The cushioning on these is wonderful.  Before I bought these I was wearing an admittedly too old pair of flip flops around the house which were leaving me with a feeling of a bruised heel and over-extended arch.  Once I started wearing the OOFOS, the bruised heel went away.  The ding in my rating, though, comes from the unisex sizing.  For someone like me with narrow feet unisex-sized shoes are too wide.  This makes it possible for my foot to slip out of the foot bed of the shoe, and for my toes to overhang the front.  Because of this, wearing the OOFOS only marginally helped the over-extended arch.
