World Rugby says rugby footwear should suit the playing surface, and studs must be no longer than 21 millimeters with no burrs or sharp edges. Gilbert's buyer guide describes soft-ground boots for wet, softer pitches and shorter molded studs for firm ground, while backs should still choose the sole for their venue before prioritizing position-specific fit.
For a back choosing rugby boots, start with the surface and conditions, then compare fit and boot weight. World Rugby says footwear should be in good condition and appropriate to the playing surface; its Regulation 12 stud specification sets the match limits.
Soft ground vs firm ground
| Choice | Manufacturer guidance | What to check |
|---|---|---|
| Soft-ground (SG) | Gilbert describes its SG boots for softer or wet conditions, with replaceable studs on some models | Whether the studs are removable, their exact length and the maker’s surface label |
| Firm-ground (FG) | Gilbert describes shorter molded studs for firmer pitches | The molded stud layout, surface guidance and fit across the forefoot |
| Artificial or 4G | Product ranges may use a separate artificial-ground label or firm-ground outsole | The venue’s footwear policy and the specific model’s maker guidance |
These labels are manufacturer categories, not a substitute for the pitch’s condition or local rules. A firm pitch can become soft after rain; a synthetic venue can have its own stud restrictions. Check the surface on the day and bring a second pair if the venue’s conditions or policy are uncertain.
Check stud condition and rules
World Rugby’s specification caps stud length at 21 millimeters and requires studs to have no burring or sharp edges. Replace worn or damaged removable studs only with components intended for that boot, and follow the boot maker’s fitting instructions. A referee can still rule on footwear at the match.
Position still matters after surface
Backs may prefer a different boot shape or upper feel from a forward, but position does not override the need for a suitable outsole. Use the broader rugby boots by position guide to compare fit and role after choosing the right surface category. For rules on what equipment may be worn, see World Rugby Regulation 12 and browse rugby boots.

Common questions
Are firm-ground or soft-ground boots better for rugby backs?
Choose for the pitch first. World Rugby says footwear must be appropriate to the playing surface; boot labels and stud layouts vary by manufacturer.
How long can rugby studs be?
World Rugby Regulation 12 sets a maximum length of 21 millimeters and bars burrs or sharp edges.
Can rugby backs wear an eight-stud boot?
The law does not assign stud patterns by position. Check the exact boot, pitch conditions and competition rules.
What rugby boots should I wear on artificial turf?
Check the footwear maker's surface guidance and the venue's rules. Do not assume a soft-ground boot is suitable for artificial turf.
