Abstract
The present invention teaches an article of footwear having a non-clogging for use on natural grass and also artificial turf surfaces. A preferred sole can include protrusions comprising a hydrophobic material having a wettability index equal to or greater than 90 degrees. The sole can include protrusions having a width at the tip in the range between 2–4 mm, a height in the range between 3–6 mm, and the closest portion of adjacent protrusions can be spaced at least 3 mm apart. In particular, the closest portion of adjacent protrusions can be spaced in the range between 3–6 mm. An alternate sole can include protrusions and traction members comprising a hydrophobic material. The present invention also teaches novel detachable cleats for use with an article of footwear.
