Sizing is in men's sizing (women order 2 sizes up- so a size 6 is equivalent to a women's 8)

Revolutionary OOfoam™ technology absorbs 37% more impact than traditional footwear foam materials to reduce the stress on your feet and joints.

• If you normally wear a whole size: Order the same whole size OOFOS.
• If you normally wear a half size: Order a half size DOWN for best fit. Women: order a half size UP for best fit.
