Abstract
The method of providing cleats on a boot sole to provide traction in all directions, that includes the steps providing the cleats to have profiles with short and long axes, locating the cleats to extend on the sole in criss-cross diagonal row configuration, the cleats oriented to have their long axes extending at positive and negative angles relative to the direction of the sole.

The method of providing cleats on a boot sole to provide traction in all directions, the sole having a longitudinal length direction and a lateral width direction, that includes the steps:
- a) providing the cleats to have profiles with short and long axes, the majority of the cleats having generally elliptical peripheral configuration,
- b) locating the cleats to extend on the sole in criss-cross diagonal row configuration, the cleats oriented to have their long axes extending at positive and negative angles relative to the longitudinal length direction of the sole, the long axes of the cleats in each row angled relative to the row length detection,
- c) said row configurations also characterized by multiple rows differently curving along their lengths, and by gaps defined between successive cleats in said curved rows, the gaps everywhere spaced away from all other nearest cleats.
In combination with a boot or shoe sole,
- a) spaced cleats extending in criss-cross diagonal row arrangement relation to the length direction of the sole, and defining multiple rows,
- b) the majority of said cleats having generally elliptical peripheral configuration, with short and long axes,
- c) successive cleats in each row having their said long axes extending in parallel relation and generally at angles to the direction of that row, said multiple rows curving along their lengths,
- d) there being gaps defined between successive generally elliptical cleats in said curved rows, the gaps being everywhere spaced away from all other nearest cleats.
