Shoe cleats (Rule  9-2-2-d) must conform to the following
specifications:
- 
They may not be more than ½-inch in length (measured from tip of cleat to the
shoe).
(See below for an exception for detachable cleats.)
- 
They may not be made of any material that burrs, chips or fractures.
- 
They may not have abrasive surfaces or cutting edges.
- 
Nondetachable cleats only may not be made of any metallic material.
- 
Detachable cleats:
- 
Must have an effective locking device.
- 
May not have concave sides.
- 
If conical they may not have flat free ends not parallel to their bases or
less than 3/8-inch in diameter or rounded free ends having arcs greater
than 7/16-inch.
- 
If oblong they may not have free ends not parallel with bases or that measure
less than 1/4-inch by 3/4-inch.
- 
If circular or ring shaped they must have rounded edges and a wall at
least 3/16-inch thick.
- 
If steel-tipped they must contain low carbon steel of 1006 material,
case hardened to .005-.008 depth and drawn to Rockwell hardness of
approximately C55.
 
 
NOTE:
The distance in paragraph (a) for detachable cleats may exceed ½-inch
if the cleat is attached to a 5/32-inch or less raised platform wider
than the base of the cleat and extended across the width of the shoe to
within 1/4-inch or less of the outer edges of the sole.
A single toe cleat does not require a raised platform that extends across
the width of the sole.
The raised platform of the toe cleat is limited to 5/32-inch or less.
The 5/32-inch or less is measured from the lowest point of the platform
to the sole of the shoe.
