wherein each looping attachment includes a compression snap and is configured to thread through a reinforced grommet and fasten a loop closed via a male portion of the snap snapping into a female portion of the snap, thereby retaining the grommet in the loop and attaching the sole to the upper;
wherein the male portion of the compression snap includes a stud and the female portion of the compression snap includes a socket having a pressure fit mechanism for gripping the stud when the stud is inserted into the socket; and
wherein each reinforced grommet includes—
threaded bolts,
a grommet bolt side having bolt openings for the threaded bolts,
a grommet sleeve side having threaded sleeves configured to engage with the threaded bolts, and
wherein each reinforced grommet is installed in an upper opening formed in the upper by placing the grommet bolt side adjacent to the upper opening on one side of the upper, placing the grommet sleeve side adjacent to the upper opening on the other side of the upper, and passing the bolts through the bolt openings and screwing the bolts into the threaded bolt sleeves.
8. The article of footwear of claim 7 wherein a first upper strap and a first lower strap are disposed between toes of a wearer, a second upper strap and a second lower strap are disposed on one side of an ankle of the wearer, and a third upper strap and a third lower strap are disposed on another side of the ankle of the wearer.
