Hi everyone. I apologize in advance for such a simplistic question, but I can't find an answer elsewhere. Are these boots legal? They have a little grip at the front of the boot and I am concerned that it may qualify as a toe stud. http://www.asics.com.au/catalogue.asp?product=1702 (In case the link doesn't work they're Asics Gel-Lethal Hybrids.) They're the most comfortable shoe to ever grace my foot, but I want to make sure they're legal for rugby before I spend that kind of money. Thank you for any responses!
