Cleat identity Establishes which meaning and rope-securing configuration the entry represents.
Term boundary
Resolves the intended physical kind before applying operating assumptions.
Rope-fitting sense
Record evidence that the intended cleat is a line-securing fitting; this draft's interpretation remains provisional.
- Does the originating registry record identify a rope fitting, footwear component, cycling interface or construction component? boundary
- Which original identifier, description or image establishes the intended meaning? provenance
Securing configuration
Identifies the features responsible for holding the line.
Holding mechanism
Describe whether the line is retained by wraps around horns, moving cams, a wedging groove or another documented mechanism.
- Which physical features retain the line, and does retention require a particular wrap or engagement sequence? definition
- What distinguishes this fitting from a fairlead, bollard or line clutch in its documented use? boundary
Line engagement Models the match between the cleat, the line and the method of securing it.
Line compatibility
Captures the supported line properties and relevant contact dimensions.
Supported line envelope
Record documented diameter and construction requirements without treating physical fit as proof of compatibility.
- What line diameter range in millimetres is supported for this configuration? measurement
- Which line materials, constructions or surface conditions are included or excluded by the supporting instructions? provenance
Engagement and release
Describes how a line becomes secured and how that state is intentionally ended.
Secure-state evidence
Define configuration-specific evidence of correct engagement and the prerequisites for release.
- What wrap pattern, seating position or cam engagement demonstrates correct securing according to the applicable instructions? action
- What load relief and line movement are required before and during intentional release? action
Installed load path Connects line loading through the cleat and attachment into its support.
Attachment and support
Records the mounting arrangement relevant to retaining the cleat under load.
Mounting evidence
Identify the attachment method and the support conditions required by installation instructions.
- How is the cleat attached, and what fasteners, backing or other attachment provisions are specified? provenance
- Does the observed installation satisfy the documented attachment and support requirements? action
Load envelope
Associates load evidence with direction, installation and operating conditions.
Conditional load rating
Keep working, proof and breaking loads distinct, and retain the conditions under which each value applies.
- What load values in newtons or kilonewtons are documented, and which rating type does each represent? measurement
- Which lead directions, mounting arrangements and static or dynamic conditions were included in the rating? provenance
- Is the proposed use supported by that evidence, or does it require an unresolved installation or load assessment? action
Retention condition Tracks deterioration that can compromise line retention, line integrity or controlled release.
Contact and mechanism condition
Examines the surfaces and moving parts responsible for engagement.
Grip and chafe inspection
Record observed contact-surface damage, obstruction and mechanism behaviour using criteria appropriate to the configuration.
- Are there burrs, cracks, worn gripping features or contamination at the line-contact surfaces? measurement
- For a configuration with moving parts, do those parts engage and return as specified by its inspection instructions? action
Service decision
Connects cleat-specific observations and incident history to permitted continued use.
Continued-use basis
Record the evidence for continued service, maintenance or withdrawal, including slipping and attachment movement.
- Has the cleat slipped, released unexpectedly, deformed or moved at its mounting, and under what recorded conditions? provenance
- Which documented criteria require cleaning, adjustment, replacement or withdrawal before the next use? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
A cleat is a protruding part or screw-in tip under the sole of a shoe, designed to resist slipping and improve traction on suitable surfaces.
In scope
- Integral sole projections and replaceable traction tips are included.
- Cleat geometry, material and contact with the ground are included.
- Attachment to the shoe sole and compatibility with its mounting interface are included.
- Traction and use restrictions for intended surfaces and activities are included.
- Wear, damage and evidence supporting continued use are included.
Out of scope
- Complete shoes are excluded except for their interfaces with traction cleats.
- Cycling shoe cleats and pedal engagement systems are excluded.
- Nautical rope-securing fittings are excluded.
- Construction cleats used to support or join components are excluded.
- Independent models of playing surfaces and sports equipment are excluded.
- Clinical assessment of the wearer's gait or injuries is excluded.
Why it exists Filled
Enable an agent to recognise a footwear traction cleat, assess its compatibility and condition, and identify appropriate use restrictions for the shoe, wearer and surface.
Distinguishing features Filled
- It projects beneath a shoe sole to improve traction through contact with or penetration into a suitable surface.
- It may be integral to the sole or attached as a replaceable tip, including a screw-in design.
- Its ground-traction function distinguishes it from a cycling cleat intended to engage a pedal.
- It is a component or feature of footwear rather than the complete cleated shoe.
- Its suitability depends on the intended surface, activity and shoe compatibility rather than projection shape alone.
What robots and AI may and may not do Filled
Must not
- Recommend use of loose, broken or incompatible cleats.
- Claim that cleats prevent all slipping or injury.
- Recommend cleats contrary to documented surface restrictions or venue rules.
- Assist in using cleats to injure people.
Only with a human decision
- Uncertain attachment integrity or shoe compatibility requires assessment by a competent person before use.
- Decisions about use following an injury require appropriate human assessment.
May
- Identify footwear traction cleats and describe their documented surface compatibility.
- Record visible wear, damage or missing cleats and flag uncertainty about serviceability.
- Explain applicable footwear restrictions for a venue or activity.
Moral aspects Filled
- Cleat selection and condition affect the safety of the wearer and other participants.
- Respecting surface restrictions helps prevent damage to shared facilities.
- Traction claims should reflect documented limitations.
Who is affected
- Wearers are affected.
- Other participants and nearby people are affected.
- Facility owners and maintenance staff are affected.
Owners Filled
Steward
The footwear owner or the organisation responsible for issued footwear.
