An ankle foot orthosis for remediation of foot drop symptoms includes a flexible cuff formed of a panel having an inner foam substrate to which is bonded an outer layer of stretchable fabric having looped fibers. A pair of dorsiflexor support straps include lace segments which are threaded through lower shoelace eyelets. The lace segments are tied together at the shoe. A hook element fastener strip is attached to the opposite end of each lace segment. The support straps cross one another over the shoe vamp and the fastener strips are secured to the sides and wrapped about the rear of the cuff.
