Abstract A parachute foot support stirrup for preloading the leg muscles of a parachutist. The foot support stirrup comprises a strapping member defining a footrest portion dimensioned to receive the feet of the parachutist and an attachment portion for removable securement of the strapping member to a fixed attachment part located above the feet of the parachutist. The footrest portion provides a support means to maintain the leg muscles of the parachutist preloaded prior to the parachutist landing on solid ground.
