Footholds, foot straps and tray mats, IHRA

IHRA answers this part for 15 of its classes. 0 of those answers permit the part outright and 14 permit it with stated conditions, leaving 1 that do not. 1 of the ones that do not are classes we read as open rather than as refusing it. 1 are inferred from how the class is written rather than quoted from a rule naming this part.

This page is IHRA only, and the bodies do not agree. The same part under IJSBA. Which one applies to you is decided by whoever sanctions the race you enter.

This is one body's answer, not the sport's. You are bound by whichever body sanctions the event you enter. If you race more than one series, build to the stricter answer. The differences are set out in the rulebook comparison.

Where it stands, class by class

15 classes, grouped where the same rule gives the same answer rather than listed one by one, because an answer that holds for a class usually holds for every class that borrows its rules.

What each answer below means

Legal, with conditions

Keep it, but measure it: the rules permit this part only inside stated limits.

No rule, this is an open class

Probably keep it. The class carries no stock clause at all, so anything unlisted appears to be open. The rulebook does not say so in terms, and this is our reading rather than a permission anybody wrote down.

Legal, with conditions 10 classes

Mat kits and padding are allowed in every class by the general rules (J.14), which overrides the closed-list default. Footholds and foot straps are not named there, so they stay not permitted. · J.14

Legal, with conditions 1 class

What we corrected here, and when

• Four-Stroke Ski Lites. Corrected 2026-10-02: the Four-Stroke Ski Lites row read the closed-list default and refused a mat kit, which J.14, in the general rules for all classes, allows.
• Ski 1100 Modified. Corrected 2026-10-02: the Ski 1100 Modified row read the closed-list default and refused a mat kit, which J.14, in the general rules for all classes, allows.
• Ski 1500 Modified. Corrected 2026-10-02: the Ski 1500 Modified row read the closed-list default and refused a mat kit, which J.14, in the general rules for all classes, allows.
• Ski GP. Corrected 2026-10-02: the Ski GP row said the part must remain OEM, where K.8.5 only requires the footwells blocked off and K.8.1 allows alterations for aftermarket footholds.
• Ski GP2. Corrected 2026-10-02: the Ski GP2 row read the closed-list default and refused a mat kit, which J.14, in the general rules for all classes, allows.

• Ski Lites. Corrected 2026-09-21: this row had read the closed-list default, which would have refused a mat kit the general rules allow. Corrected 2026-10-02: J.14 names mats and padding, not footholds or foot straps, so this row now says so.
• Ski Vintage. Corrected 2026-10-02: the Ski Vintage row read the closed-list default and refused a mat kit, which J.14, in the general rules for all classes, allows.
• Sport GP. Corrected 2026-10-02: the Sport GP row read the closed-list default and refused a mat kit, which J.14, in the general rules for all classes, allows.

• X2 Vintage. Corrected 2026-10-02: the X2 Vintage row said the part must remain OEM, where T.6.6 only requires the footwells blocked off and J.14 allows mat kits in every class.
