Abstract: Shoes which by their construction avoid twisting stress which save especially the knees of humans and lower legs of horses from serious injury are shoes which are equipped with “Turn-Table” topped outsold disc treads of simple anti-friction design upon which top surface said shoes can rotate on to any 360 degree direction while said outsole bottom surface tread is frictionally adhered to a footing surface with said shoe outsole discs that resist any linear free wheeling motion or footing slippage even when said shoe is substantially tilted to a rapid action canted positional arrangement with a footing surface due to substantial disc perimeter tread flexibility.

Abstract: The construction and arrangement of projectile bearing surface interfaces rearward and forward of a recessed surface chamber of the projectile interface conjointly with the interfaces of bore wall areas segmented by recessed bore chambers which in conjunction effect the deployment/transport/dispersement/development/modulation and transformation of explosive propellant charges sequentially primed and activated rearward and forwardly of the projectile along the bore and in bore wall chambers captively converting high static gas pressure to expansively relieved dynamic propellant gas pressure directly at the projectile reducing firearm barrel recoil while energizing projectile movement along the bore in a closed-system of thermodynamic propellant energy for free flight purposes.
