Abstract
A shoe with a sole, upper, and shaft, whose upper and shaft contain a number of modifications to increase flexibility of the shoe but maintain protection for the wearer of the shoe. These modifications fall into the general categories of notch and aperture. The upper also has a number of protrusions into the shaft to increase protection in the protrusion areas. The location, shape, and size of these notches, apertures, and protrusions are important for optimizing the flexibility and protective qualities of the shoe.
