A method and apparatus for enhancing the ability of a human to run and jump with comfort comparable to running barefoot on a trampoline and with control comparable to that of the unaided human form, yet with freedom from ankle-turning roll moments associated with substantial ground contact member (GCM) extension downwardly away from the sole of the foot including, a resiliently urged GCM constrained to two degrees of freedom: translation away from the sole of the user's foot and rotation about a longitudinal axis at ground level. The apparatus relates flexure of a GCM toe pressure member to comparable flexure of user's toes at the metatarsal joints. The apparatus also incorporates lower leg to ankle pivot bracing, and extends the GCM in downward direction parallel to the lower leg while mimicking user ankle articulation with parallelism-maintaining rotation about a downwardly resiliently urged transverse pivot axis similar to the user's own ankle joint for extended travel.
