-------------------------- ALUMINIUM STUDS (and similar plastic designs) The number, layout and length (diameters are controlled by the Laws). Speed versus Grip A back would ideally want to wear running shoes, (I have met some forwards who would as well !!! --- ). Spikes give maximum penetration and grip with minimum removal force. Increasing the length of the stud under soft conditions improves grip. The number of studs is a balance between penetration, and traction (less studs in hard conditions more in soft). Excessive studs can result in clogging in muddy conditions, which adds dead weight and reduces grip.
General Rules Six or seven studs for boot sizes (UK) 7 to 10. Four or five on the ball of the sole and two on the heel. Smaller boots six studs, larger seven to nine. Less studs for light players, more for heavy. Short studs for speed and dry conditions. Long studs for traction especially in muddy conditions. Short studs may be last seasons 'long studs' worn down, but make sure they comply with the laws!Rubber Ridged Sole Boots (RRSB formerly known as blades) I know only of the two RFU approved versions of RRSB's these are by CICA and are called Grass Runner and Mud Runner. The Grass Runner has the most 'studs' but these are shorter than the Mud version. Two of my sons are currently using these and have done so since the beginning of the 95/96 season. They have not found any problems. At present they appear to have a lower wear rate than aluminium studs, but being moulded, when they are worn down the boots are scrap.
I am trying to compile data about boots used to play Rugby. This data will be published here in the WWW as it becomes available.
