Re: SmartPower Profiler stud set
we have done this before -- but the key bits are
Studs of players’ boots must conform to the “Safety Aspects of Rugby
Boot Sole Design” set out below:” (Appendix 2 hereto)
The following guidelines provide guidance on the design, dimensions and
performance of rugby studs/cleats.
Suitable performance tests are
suggested which can be used to evaluate the performance of new
stud/cleat designs
The performance criterion for tests A and B is that
the stud/cleat be
evaluated should cause no greater damage to the artificial skin than the
reference stud/cleat defined in Figure 1 above
SmartPower will tell you they have performed some tests and their profiler studs caused no greater damage than the reference stud. Hence they meet the regulation, hence they are 'world rugby approved'
Note that they don't even have to perform those exact tests, which are only
suggested tests. Just
some tests.
