Our unique O2 Motion air pod has been re-invented to not only provide superior cushioning, but to assist in effortless heel rebound. A torsion stabiliser system provides increased stability between the heel and forepart, and dramatically reduces weight in the shoe. Flex channels in the forepart enhance the natural walking motion of the foot. A removable footbed features anatomical arch support that cradles the foot. Back pull tab provides easy on-off wear.
